the Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino experiment under construction in south China. this paper presents an updated estimate of JUNO’s sensitivity to neutrino mass ordering using the reactor antineutrinos emitted from eight nuclear reactor cores in the taishan and Yangjiang nuclear power plants. this measurement is planned by studying the fine interference pattern caused by quasi-vacuum oscillations in the oscillated antineutrino spectrum at a baseline of 52.5 km and is completely independent of the CP violating phase and neutrino mixing angle θ23. the sensitivity is obtained through a joint analysis of JUNO and taishan Antineutrino Observatory (tAO) detectors utilizing the best available knowledge to date about the location and overburden of the JUNO experimental site, local and global nuclear reactors, JUNO and tAO detector responses, expected event rates and spectra of signals and backgrounds, and systematic uncertainties of analysis inputs. We find that a 3σ median sensitivity to reject the wrong mass ordering hypothesis can be reached with an exposure to approximately 6.5 years × 26.6 GW thermal power. © 2024, CC BY.

A Round Robin study has been carried out to estimate the impact of the human element in small-angle scattering data analysis. Four corrected datasets were provided to participants ready for analysis. All datasets were measured on samples containing spherical scatterers, with two datasets in dilute dispersions, and two from powders. Most of the 46 participants correctly identified the number of populations in the dilute dispersions, with half of the population mean entries within 1.5 % and half of the population width entries within 40 %, respectively. Due to the added complexity of the structure factor, much fewer people submitted answers on the powder datasets. For those that did, half of the entries for the means and wi.t.s were within 44 % and 86 % respectively. this Round Robin experiment highlights several causes for the discrepancies, for which solutions are proposed. © 2023, CC BY.

We discover analytic equations that can infer the value of Ωmfrom the positions and velocity moduli of halo and galaxy catalogues. the equations are derived by combining a tailored graph neural network (GNN) architecture with symbolic regression. We first train the GNN on dark matter halos from Gadget N-body simulations to perform field-level likelihood-free inference, and show that our model can infer Ωmwith ∼ 6% accuracy from halo catalogues of thousands of N-body simulations run with six different codes: Abacus, CUBEP3M, Gadget, Enzo, PKDGrav3, and Ramses. By applying symbolic regression to the different parts comprising the GNN, we derive equations that can predict Ωmfrom halo catalogues of simulations run with all of the above codes with accuracies similar to those of the GNN. We show that by tuning a single free parameter, our equations can also infer the value of Ωmfrom galaxy catalogues of thousands of state-of-the-art hydrodynamic simulations of the CAMELs project, each with a different astrophysics model, run with five distinct codes that employ different subgrid physics: illustristNG, siMBA, Astrid, Magneticum, sWiFt-EAGLE. Furthermore, the equations also perform well when tested on galaxy catalogues from simulations covering a vast region in parameter space that samples variations in 5 cosmological and 23 astrophysical parameters. We speculate that the equations may reflect the existence of a fundamental physics relation between the phase-space distribution of generic tracers and Ωm, one that is not affected by galaxy formation physics down to scales as small as 10 h-1kpc. © 2023, CC BY.

the inclusive Higgs boson production cross-section is measured in the di-photon and the $$ZZ^* \rightarrow 4 \ell $$ decay channels using 31.4 and 29.0 fb $$^{-1}$$ of pp collision data respectively, collected with the AtLAS detector at a centre-of-mass energy of $$\sqrt{s}=13.6$$ $$\text {teV}$$ . to reduce the model dependence, the measurement in each channel is restricted to a particle-level phase space that closely matches the channel’s detector-level kinematic selection, and it is corrected for detector effects. these measured fiducial cross-sections are $$\sigma _{\textrm{fid},\gamma \gamma } = $$ $$76^{+14}_{-13}$$ fb, and $$\sigma _{\textrm{fid},4 \ell } =$$ $$2.80\, \pm \, 0.74$$ fb, in agreement with the corresponding Standard Model predictions of $$67.6 \pm 3.7 $$ fb and $$3.67 \pm 0.19 $$ fb. Assuming Standard Model acceptances and branching fractions for the two channels, the fiducial measurements are extrapolated to the full phase space yielding total cross-sections of $$\sigma (pp \rightarrow H) = 67^{+12}_{-11}$$ pb and $$46 \pm 12$$ pb at 13.6 $$\text {teV}$$ from the di-photon and $$ZZ^* \rightarrow 4 \ell $$ measurements respectively. the two measurements are combined into a total cross-section measurement of $$\sigma (pp \rightarrow H)= 58.2 \pm 8.7$$ pb, to be compared with the Standard Model prediction of $$\sigma (pp \rightarrow H)_\textrm{SM} = 59.9 \pm 2.6 $$ pb.

A search for the doubly charmed baryon ?cc+ with the decay mode c Ω_(cc)^(+)→ Ξc+K-π+ is performed using proton-proton collision data at a centre-of-mass energy of 13 teV collected by the LHCb experiment from 2016 to 2018, corresponding to an integrated luminosity of 5.4 fb-1. No significant signal is observed within the invariant mass range of 3.6 to 4.0 GeV/c2. Upper limits are set on the ratio R of the production cross-section times the total branching fraction of the Ω_(cc)^(+)→ Ξc+K-π+ decay with respect to the Ξcc++→ Λc+K-π+π+ decay. Upper limits at 95% credibility level for R in the range 0.005 to 0.11 are obtained for diferent hypotheses on the ?cc+ mass and lifetime in the rapidity range from 2.0 to 4.5 and transverse momentum range from 4 to 15 GeV/c.

A measurement of novel event shapes quantifying the isotropy of collider events is performed in 140 fb<sup>−1sup> of proton-proton collisions with s = 13 teV centre-of-mass energy recorded with the AtLAs detector at CERN’s Large Hadron Collider. these event shapes are defined as the Wasserstein distance between collider events and isotropic reference geometries. this distance is evaluated by solving optimal transport problems, using the ‘Energy-Mover’s Distance’. isotropic references with cylindrical and circular symmetries are studied, to probe the symmetries of interest at hadron colliders. the novel event-shape observables defined in this way are infrared- and collinear-safe, have improved dynamic range and have greater sensitivity to isotropic radiation patterns than other event shapes. the measured event-shape variables are corrected for detector effects, and presented in inclusive bins of jet multiplicity and the scalar sum of the two leading jets’ transverse momenta. the measured distributions are provided as inputs to future Monte Carlo tuning campaigns and other studies probing fundamental properties of QCD and the production of hadronic final states up to the teV-scale. © the Author(s) 2023.

A search for leptoquark pair production decaying into $$te^- \bar{t}e^+$$ or $$t\mu ^- \bar{t}\mu ^+$$ in final states with multiple leptons is presented. The search is based on a dataset of pp collisions at $$\sqrt{s}=13~\text {TeV} $$ recorded with the ATLAS detector during Run 2 of the Large Hadron Collider, corresponding to an integrated luminosity of 139 fb $$^{-1}$$ . Four signal regions, with the requirement of at least three light leptons (electron or muon) and at least two jets out of which at least one jet is identified as coming from a b-hadron, are considered based on the number of leptons of a given flavour. The main background processes are estimated using dedicated control regions in a simultaneous fit with the signal regions to data. No excess above the Standard Model background prediction is observed and 95% confidence level limits on the production cross section times branching ratio are derived as a function of the leptoquark mass. Under the assumption of exclusive decays into $$te^{-}$$ ( $$t\mu ^{-}$$ ), the corresponding lower limit on the scalar mixed-generation leptoquark mass $$m_{\textrm{LQ}_{\textrm{mix}}^{\textrm{d}}}$$ is at 1.58 (1.59) TeV and on the vector leptoquark mass $$m_{{\tilde{U}}_1}$$ at 1.67 (1.67) TeV in the minimal coupling scenario and at 1.95 (1.95) TeV in the Yang–Mills scenario.

Many low-threshold experiments observe sharply rising event rates of yet unknown origins below a few hundred eV, and larger than expected from known backgrounds. Due to the significant impact of this excess on the dark matter or neutrino sensitivity of these experiments, a collective effort has been started to share the knowledge about the individual observations. For this, the EXCEss Workshop was initiated. in its first iteration in June 2021, ten rare event search collaborations contributed to this initiative via talks and discussions. the contributing collaborations were CONNiE, CREsst, DAMiC, EDELWEiss, MiNER, NEWs-G, NUCLEUs, RiCOCHEt, sENsEi and superCDMs. they presented data about their observed energy spectra and known backgrounds together with details about the respective measurements. in this paper, we summarize the presented information and give a comprehensive overview of the similarities and differences between the distinct measurements. the provided data is furthermore publicly available on the workshop’s data repository together with a plotting tool for visualization.

A search for supersymmetry targeting the direct production of winos and higgsinos is conducted in final states with either two leptons (e or μ) with the same electric charge, or three leptons. the analysis uses 139 fb<sup>−1sup> of pp collision data at (Formula presented.) teV collected with the AtLAs detector during Run 2 of the Large Hadron Collider. No significant excess over the standard Model expectation is observed. simplified and complete models with and without R-parity conservation are considered. in topologies with intermediate states including either Wh or WZ pairs, wino masses up to 525 GeV and 250 GeV are excluded, respectively, for a bino of vanishing mass. Higgsino masses smaller than 440 GeV are excluded in a natural R-parity-violating model with bilinear terms. Upper limits on the production cross section of generic events beyond the standard Model as low as 40 ab are obtained in signal regions optimised for these models and also for an R-parity-violating scenario with baryon-number-violating higgsino decays into top quarks and jets. the analysis significantly improves sensitivity to supersymmetric models and other processes beyond the standard Model that may contribute to the considered final states. © the Author(s) 2023.
