    <jats:p> In recent neutrino detectors, neutrons produced in neutrino reactions play an important role. Muon capture on oxygen nuclei is one of the processes that produce neutrons in water Cherenkov detectors. We measured neutron multiplicity in the process using cosmic ray muons that stop in the gadolinium-loaded Super-Kamiokande detector. For this measurement, neutron detection efficiency is obtained with the muon capture events followed by gamma rays to be <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"> <a:msubsup> <a:mn>50.2</a:mn> <a:mrow> <a:mo>−</a:mo> <a:mn>2.1</a:mn> </a:mrow> <a:mrow> <a:mo>+</a:mo> <a:mn>2.0</a:mn> </a:mrow> </a:msubsup> <a:mo>%</a:mo> </a:math> .

    <jats:title> A <jats:sc>bstract</jats:sc> </jats:title> <jats:p> A search for signatures of a dark analog to quantum chromodynamics is performed. The analysis targets long-lived dark mesons that decay into standard-model particles, with a high branching fraction of the dark mesons decaying into muons. The dark mesons are formed by the hadronisation of dark partons, which are produced by a decay of the Higgs boson.

    <jats:p>The 2x2 Demonstrator, a prototype for the Deep Underground Neutrino Experiment (DUNE) liquid argon (LAr) Near Detector, was exposed to the Neutrinos from the Main Injector (NuMI) neutrino beam at Fermi National Accelerator Laboratory (Fermilab). This detector is a prototype of a new modular design for a liquid argon time-projection chamber (LArTPC), comprising a two-by-two array of four modules, each further segmented into two optically isolated LArTPCs. The 2x2 Demonstrator features a number of pioneering technologies, including a low-profile resistive field shell to establish drift fields, native 3D ionization pixelated imaging, and a high-coverage dielectric light readout system. The 2.4-tonne active mass detector is flanked upstream and downstream by supplemental solid-scintillator tracking planes, repurposed from the MINERvA experiment, which track ionizing particles exiting the argon volume. The antineutrino beam data collected by the detector over a 4.5 day period in 2024 include over 30,000 neutrino interactions in the LAr active volume—the first neutrino interactions reported by a DUNE detector prototype. During its physics-quality run, the 2x2 Demonstrator operated at a nominal drift field of 500 V/cm and maintained good LAr purity, with a stable electron lifetime of approximately 1.25 ms. This paper describes the detector and supporting systems, summarizes the installation and commissioning, and presents the initial validation of collected NuMI beam and off-beam self-triggers. In addition, it highlights observed interactions in the detector volume, including candidate muon antineutrino events.</jats:p>

    <jats:title> A <jats:sc>bstract</jats:sc> </jats:title> <jats:p> An analysis of the flavour structure of dimension-6 effective field theory (EFT) operators in multilepton final states is presented, focusing on the interactions of quarks with Z bosons. For the first time, the flavour structure of these operators is disentangled by simultaneously probing the interactions with different quark generations. The analysis targets the associated production of a top quark pair and a Z boson, as well as diboson processes in final states with at least three leptons, which can be electrons or muons. The data were recorded by the CMS experiment in the years 2016–2018 in proton-proton collisions at a centre-of-mass energy of 13 TeV and correspond to an integrated luminosity of 138 fb <jats:sup> <jats:italic>−</jats:italic> 1 </jats:sup> . Consistency with the standard model of particle physics is observed and limits are set on the selected Wilson coefficients, split into couplings to light- and heavy-quark generations. </jats:p>

Events are selected based on the presence of either two leptons with the same electric charge or three leptons, and multiple jets and b-tagged jets. We present measurements of differential production cross sections as a function of kinematic variables sensitive to different aspects of the process modeling, using a multivariate discriminator in the two-lepton selection region and a simple selection-based method in the three-lepton region. The normalized cross section measurements are generally consistent with the standard model expectations, while we observe larger values compared to the expectations in the absolute cross section measurements, consistent with previous inclusive cross section measurements. In addition, we measure the leptonic charge asymmetry of this process, obtaining an observed value of <jats:inline-formula> <jats:alternatives> <jats:tex-math>$$ {A}_c^{\ell }=-{0.19}_{-0.18}^{+0.16} $$</jats:tex-math> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msubsup> <mml:mi>A</mml:mi> <mml:mi>c</mml:mi> <mml:mi>鈩</mml:mi&g

    <jats:title> A <jats:sc>bstract</jats:sc> </jats:title> <jats:p> A model-independent measurement of the differential production cross section of the Higgs boson decaying into a pair of W bosons, with a final state including two jets produced in association, is presented. In the analysis, events are selected in which the decay products of the two W bosons consist of an electron, a muon, and missing transverse momentum. The model independence of the measurement is maximized by employing a discriminating variable, developed through machine learning, that is agnostic to the signal hypothesis. The analysis is based on proton-proton collision data at <jats:inline-formula> <jats:alternatives> <jats:tex-math>$$ \sqrt{s}=13 $$</jats:tex-math> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msqrt> <mml:mi>s</mml:mi> </mml:msqrt> <mml:mo>=</mml:mo> <mml:mn>13</mml:mn> </mml:math> </jats:alternatives> </jats:inline-formula> TeV collected with the CMS detector from 2016–2018, corresponding to an integrated luminosity of 138 fb <jats:sup>−1</jats:sup> .

    <jats:title> A <jats:sc>bstract</jats:sc> </jats:title> <jats:p> A measurement is presented of the electroweak vector boson scattering production of ZV (V = W, Z) boson pairs associated with two jets in proton-proton collisions at a center-of-mass energy of 13 TeV. The data, corresponding to an integrated luminosity of 138 fb <jats:sup>−1</jats:sup> , were collected at the CERN LHC with the CMS detector during the 2016–2018 data-taking period. The analysis targets final states with a pair of isolated electrons or muons from Z boson decays and three or four jets, depending on the momentum of the vector boson that decays into quarks. Signal strength is measured for events characterized by a large invariant mass of two forward jets with a wide pseudorapidity gap between them. The electroweak production of ZV in association with two jets is measured with an observed (expected) significance of 1.3 (1.8) standard deviations. A combination of the analyses of ZV channel and the previously published WV channel in the lepton plus jets final state places constraints on effective field theory parameters that describe anomalous electroweak production of WW, WZ, and ZZ boson pairs in association with two jets. Several world best limits are set on anomalous quartic gauge couplings in terms of dimension-8 standard model effective field theory operators. </jats:p>

The detec-tor consists of an Eljen-200 plastic scintillator coupled to a Hamamatsu Photonics R7725photomultiplier tube (PMT). PMT afterpulses, delayed pulses produced after an energeticpulse, have been observed in the SUBMET readout system, especially following primarypulses with a large area. We present a prediction method for afterpulse rates based onmeasurable parameters, which reproduces the observed rate with approximately 20% pre-cision. This approach enables a better understanding of afterpulse contributions and, con-sequently, improves the reliability of background predictions

It provides various trigger sources (software, regular, random, external), throttling mechanisms and a programmable sequencer for fast commands. A data capture block for local readout of the outgoing event data through direct software access complements this development. Such integration facilitates the development of stand-alone test systems without specializedtiming/trigger distribution or DAQ hardware.

    A search for long-lived heavy neutral leptons produced in B-meson decays and decaying to a μ<sup>±</sup>π<sup>鈭</sup> final state is performed with data collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5 fb<sup>−1</sup>. The results are interpreted in both lepton-number-conserving and lepton-number-violating scenarios. No significant excess is observed. Constraints are placed on the squared mixing element |U<inf>μN</inf>|<sup>2</sup> to the active muon neutrino, under the assumption that couplings to other lepton flavours are negligible, in the mass range of 1.6–5.5 GeV.

    The first observation of single top quark production in association with a W and a Z boson in proton-proton collisions is reported. The analysis uses data at center-of-mass energies of 13 and 13.6 TeV recorded with the CMS detector at the CERN LHC, corresponding to a total integrated luminosity of 200  fb^{-1}. Events with three or four charged leptons, which can be electrons or muons, are selected. Advanced machine-learning algorithms and improved reconstruction methods, compared to an earlier analysis, result in an unprecedented sensitivity to tWZ production. The measured cross sections for tWZ production are 248±52  fb and 242±77  fb for sqrt[s]=13 and 13.6 TeV, respectively. The signal is established with a statistical significance of 5.8 standard deviations, with 3.5 expected, compared to the background-only hypothesis.

This quantity is measured to be ΔA<inf>CP</inf>=(4.03±1.18±0.23)%, where the first uncertainty is statistical and the second is systematic. When combined with the previous LHCb result, a value of ΔA<inf>CP</inf>=(4.31±1.06±0.28)% is obtained, corresponding to a significance of 3.9σ against the CP symmetry hypothesis. Studies of triple-product asymmetries, which provide an additional probe of CP violation, show no significant deviation from CP symmetry.

    A search is presented for the two-body charmed baryonic decays, B[over ¯]_{(s)}^{0}→Λ_{c}^{+}Λ[over ¯]_{c}^{-}, using a data sample collected by the LHCb experiment during 2011-2012 and 2015-2018, corresponding to an integrated luminosity of 9  fb^{-1}. The first observation of the B[over ¯]_{s}^{0}→Λ_{c}^{+}Λ[over ¯]_{c}^{-} decay is reported with 6.2σ significance along with 4.3σ evidence for the B[over ¯]^{0}→Λ_{c}^{+}Λ[over ¯]_{c}^{-} decay. The branching fractions are measured to be B(B[over ¯]^{0}→Λ_{c}^{+}Λ[over ¯]_{c}^{-})=(1.01_{-0.28}^{+0.27}±0.08±0.15)×10^{-5} and B(B[over ¯]_{s}^{0}→Λ_{c}^{+}Λ[over ¯]_{c}^{-})=(5.0±1.3±0.5±0.8)×10^{-5}, where the first uncertainty is statistical, the second systematic, and the third due to external inputs. These results provide novel experimental inputs for the theoretical framework describing two-body baryonic decays of B mesons via W-emission and W-exchange mechanisms.

    The first observation of the decay B^{+}→pΛ[over ¯] is presented using proton-proton collision data collected by the LHCb experiment between 2016 and 2018 at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4  fb^{-1}. The signal significance exceeds seven standard deviations. Using the B^{+}→K_{S}^{0}π^{+} decay as a normalization channel, the branching fraction is measured and combined with previous LHCb results based on data collected at 7 and 8 TeV in 2011 and 2012, yielding B(B^{+}→pΛ[over ¯])=(1.24±0.17±0.05±0.03)×10^{-7}, where the first uncertainty is statistical, the second is systematic, and the third comes from the uncertainty on the branching fraction of the normalization channel. The B^{+}→pΛ[over ¯] weak decay parameter is measured to be α_{B}=0.87_{-0.29}^{+0.26}±0.09, indicating the presence of comparable S-wave and P-wave decay amplitudes.

    A study of neural network architectures for the reconstruction of the energy deposited in the cells of the ATLAS liquid-argon calorimeters under high pile-up conditions expected at the HL-LHC is presented. These networks are designed to run on the FPGA-based readout hardware of the calorimeters under strict size and latency constraints. Several architectures, including Dense, recurrent (RNN), and convolutional (CNN) neural networks, are optimised using a Bayesian procedure that balances energy resolution against network size. The optimised Dense, CNN, and combined Dense+RNN architectures achieve a transverse energy resolution of approximately 80 MeV, outperforming both the optimal filtering (OF) method currently in use and RNNs of similar complexity. A detailed comparison across the full dynamic range shows that Dense, CNN, and Dense+RNN accurately reproduce the energy scale, while OF and RNNs underestimate the energy. Deep evidential regression is implemented within the Dense architecture to address the need for reliable per-event energy uncertainties. This approach provides predictive uncertainty estimates with minimal increase in network size. The predicted uncertainty is found to be consistent, on average, with the difference between the true deposited energy and the predicted energy.

    This paper presents the expected sensitivity to the neutrino oscillation parameters of the Hyper-Kamiokande long-baseline program. The Hyper-Kamiokande experiment, currently under construction in Japan, will measure the oscillations of accelerator-produced neutrinos with thousands of selected events per sample: this corresponds to an increase of statistics of a factor 25–100 with respect to recent results from the currently-running long-baseline neutrino oscillation experiment in Japan, T2K. In the most favorable scenario we will achieve the discovery of Charge-Parity (CP) violation in neutrino oscillation at 5σ C.L. in less than 3 years. With 10 years of data-taking, and assuming a neutrino : antineutrino beam running ratio of 1:3, a CP violation discovery at 5σ C.L. is possible for more than 60% of the actual values of the CP-violating phase, δCP. Moreover, we will measure δCP with a precision ranging from 20鈭, in the case of maximal CP violation, to 6鈭, in the case of CP conservation. We aim to achieve a 0.5% resolution on the Δm322 parameter, and a resolution between 3% and 0.5% on the sin2θ23 parameter, depending on its true value. These results are obtained by extending the analysis methods of T2K with dedicated tuning to take into account the Hyper-Kamiokande design: the larger far detector, the more powerful beam, the upgraded near detector ND280, and the planned additional Intermediate Water Cherenkov Detector.

The D0→KS0π+π− decay is used as calibration channel to cancel residual detection and production asymmetries.

    A search for nonresonant new physics phenomena in high-mass dilepton events produced in association with b-tagged jets is performed using proton-proton collision data collected in 2016–2018 by the CMS experiment at the CERN LHC, at a center-of-mass energy of 13 TeV corresponding to an integrated luminosity of 138 fb<sup>−1</sup>. The analysis considers two effective field theory models with dimension-six operators; involving four-fermion contact interactions between two leptons (鈩撯創, electrons or muons) and b or s quarks (bb鈩撯創 and bs鈩撯創). Two lepton flavor combinations (ee and μμ) are required and events are classified as having 0, 1, or ≥2 b-tagged jets in the final state. No significant excess is observed over the standard model backgrounds. Upper limits are set on the production cross section of the new physics signals. These translate into lower limits on the energy scale Λ of 6.9 to 9.0 TeV in the bb鈩撯創 model, depending on model parameters, and on the ratio of energy scale and effective coupling, Λ/g<inf>*</inf>, of 2.0 to 2.6 TeV in the bs鈩撯創 model. Lepton flavor universality is also tested by comparing the dielectron (ee) and dimuon (μμ) mass spectra for different b-tagged jet multiplicities. No significant deviation from the standard model expectation of unity is observed.

    Using proton-proton collision data collected by the CMS experiment at sqrt[s]=13  TeV in 2016-2018, corresponding to an integrated luminosity of 140  fb^{-1}, the first full reconstruction of the three vector B meson states, B^{*+}, B^{*0}, and B_{s}^{*0}, is performed. The mass differences between the excited mesons and their corresponding ground states are measured to be m(B^{*+})-m(B^{+})=45.277±0.039±0.027  MeV, m(B^{*0})-m(B^{0})=45.471±0.056±0.028  MeV, and m(B_{s}^{*0})-m(B_{s}^{0})=49.407±0.132±0.041  MeV, where the first uncertainties are statistical and the second are systematic. These results improve on the precision of previous measurements by an order of magnitude.

    <jats:title>Abstract</jats:title> <jats:p> In 2024, a failed supernova (SN) candidate, M31-2014-DS1, was reported in the Andromeda galaxy (M31), located at a distance of approximately 770 kpc. In this Letter, we search for neutrinos from this failed SN using data from Super-Kamiokande (SK). Based on the estimated time of black hole formation inferred from optical and infrared observations, we define a search window for neutrino events in the SK data. Using this window, we develop a dedicated analysis method for failed SNe and apply it to M31-2014-DS1, by conducting a cluster search using the timing and energy information of candidate events. No significant neutrino excess is observed within the search region. Consequently, we place an upper limit on the time-integrated electron antineutrino luminosity from M31-2014-DS1 and discuss its implications for various failed SN models and their neutrino emission characteristics. Despite the 18 MeV threshold adopted to suppress backgrounds, the search remains sufficiently sensitive to constrain the Shen-TM1 equation of state, in a more optimistic emission scenario with progenitor stars of 40 <jats:italic>M</jats:italic> <jats:sub>鈯</jats:sub> and relatively high mean electron-antineutrino energies of about 23.2 MeV, yielding a 90% confidence level upper limit of 1.76 × 10 <jats:sup>53</jats:sup> erg on the time-integrated electron antineutrino luminosity, moderately above the expected value of 1.35 × 10 <jats:sup>53</jats:sup> erg. </jats:p>
