This paper reports recent advancements in GasPM technology aimed at mitigating photon-feedback-induced time-resolution degradation through improved beam tests with a high-speed digitizer and exploring the robustness of LaB photocathodes for future detector upgrades.
This paper reports on the early operation and single-phase commissioning of Proto-0, a small-scale dual-phase argon TPC at INFN Naples designed to validate key technologies for the upcoming DarkSide-20k experiment, with a specific focus on measuring scintillation light yield using calibration sources.
Using 8 years of data from the HAWC Observatory, researchers conducted an indirect search for dark matter annihilation in the Galactic Center across masses from 1 TeV to 10 PeV, finding no significant excess and establishing the first gamma-ray constraints on particles above 100 TeV with upper limits on the annihilation cross section of approximately $10^{-24}^3$/s.
This study utilizes PYTHIA 8 and EPOS-LHC models to demonstrate that particle-identified balance functions in 13 TeV proton-proton collisions exhibit distinct dependencies on event multiplicity and spherocity, revealing that while PYTHIA 8 reflects fragmentation-dominated dynamics, EPOS-LHC captures collective effects like radial flow and diffusion that mimic heavy-ion behavior, thereby offering a powerful tool to disentangle hadronization mechanisms and medium-like collectivity in small collision systems.
This paper evaluates the impact of the first JUNO experiment results on trimaximal mixing patterns, finding that while renormalization group running can reconcile these models with data for quasi-degenerate neutrino masses, the TM2 pattern is severely constrained or ruled out by neutrinoless double beta decay and KATRIN limits in the Majorana and Dirac cases, respectively.
This paper presents the updated 2025 Physics Briefing Book for the Latin American Strategy Forum for Research Infrastructure in High Energy, Cosmology, and Astroparticle Physics (LASF4RI-HECAP), which synthesizes 46 community white papers and symposium discussions to establish a long-term strategic roadmap across seven key scientific and technical working groups.
This paper presents the first systematic lattice QCD study of proton- scattering across multiple pion masses and lattice spacings, yielding scattering parameters and cross sections that agree with experimental data and confirm attractive interactions critical for nuclear theory and neutron star modeling.
This paper demonstrates a proof-of-concept where AI agents, directed by expert physicists, independently performed a complete precision measurement of the thrust distribution in LEP ALEPH data, marking a significant step toward integrating AI into the theory-experiment loop to accelerate discoveries in fundamental physics.
This paper presents the first next-to-next-to-leading order (NNLO) QCD event generation for production matched to parton showers using the MiNNLOPS method, which incorporates a novel pointwise combination of soft and high-energy two-loop amplitude approximations to provide robust, publicly available predictions for Higgs-boson decay into photons with off-shell top-quark decays.
This paper demonstrates that different, formally equivalent resummation prescriptions for the thrust distribution in annihilation yield non-negligible numerical differences that exceed standard theoretical uncertainties, thereby necessitating more conservative error estimates in strong coupling determinations.
This paper investigates the feasibility of measuring quantum entanglement and Bell-type spin-correlation observables in tau-lepton pairs produced at the proposed Super Tau-Charm Facility, demonstrating that high-statistical-significance resolution of these effects is achievable within the Standard Model framework using realistic detector conditions and integrated luminosities.
This paper proposes that quantum sensors can detect bursts of ultralight bosonic fields emitted during violent astrophysical events, thereby establishing a new multimessenger astronomy channel that remains viable even when accounting for matter screening effects.
This paper presents environmental measurements at the Sedrun Access Shaft in Switzerland, demonstrating that its low ground motion and electromagnetic background levels make it a viable site for an 800-meter atom interferometer designed to detect ultralight dark matter and gravitational waves.
This paper introduces QUnfold, an open-source framework that reformulates the High-Energy Physics unfolding problem as a Quadratic Unconstrained Binary Optimization (QUBO) task, enabling competitive reconstruction accuracy through both classical solvers and quantum-compatible methods like D-Wave's hybrid solver.
This paper employs both machine learning techniques and an extended Gürsey-Radicati analytical formula to predict the mass spectra of fully-heavy baryons and exotic pentaquarks, offering complementary insights that align with existing experimental data while forecasting numerous unobserved states.
Using 137 fb⁻¹ of 13 TeV proton-proton collision data from the ATLAS detector, this study searches for long-lived particles via displaced vertices and missing transverse momentum, finding no significant excess over Standard Model backgrounds and setting 95% confidence-level limits on four specific beyond-the-Standard Model scenarios.
This paper reviews a decade of progress in functional QCD, detailing its technical framework and validation against lattice data to provide predictive insights into the high-density phase structure of QCD, including the potential emergence of critical endpoints, moat regimes, and inhomogeneous phases.
This paper reports the first measurement of the cosmic muon flux at the Stawell Underground Physics Laboratory using eight plastic scintillator panels, yielding a value of (6.33 ± 0.04_stat ± 0.35_sys) × 10⁻⁸ s⁻¹ cm⁻² that aligns well with simulations and features significantly reduced uncertainty compared to modeling.
This paper proposes that a minimal dark scalar with a mass of approximately 9.40 GeV, which shares high- fragmentation scaling with NRQCD color-octet production, can simultaneously explain the anomalous high- plateau and vanishing elliptic flow of in heavy-ion collisions while resolving related quarkonium polarization and detection puzzles.
Using 138 fb of proton-proton collision data at 13 TeV collected by the CMS detector, this paper presents three "mono-X" searches for invisible new physics in pencil-jet, mono-photon, and mono-top final states, finding no significant deviations from Standard Model predictions and setting stringent exclusion limits on dark matter and large extra dimension models.
