This paper proposes a novel waveform-based method that isolates shower components from muon tracks to reconstruct energy-deposition vertices in large-scale liquid scintillator detectors with high precision and efficiency, thereby enabling effective localized spatial vetoes to suppress cosmogenic backgrounds in experiments like JUNO.
Using a dataset with double the previous exposure and improved analysis techniques, the NOvA experiment reports its most precise single-experiment constraints on atmospheric neutrino mass splitting and mixing parameters, showing a mild preference for the normal mass ordering that strengthens to 87% probability when combined with Daya Bay data.
This paper proposes and analyzes a novel "synchrotron radiation power leveling" strategy for the Future Circular Collider (FCC-hh), where beam energy is dynamically adjusted during a physics store to manage heat loads from synchrotron radiation, thereby increasing both peak and integrated luminosity and significantly boosting the production rates of key physics processes like di-Higgs events.
This paper presents a comprehensive study of heavy flavor baryon spectroscopy using a quark-diquark effective mass formalism under two interaction scenarios, successfully predicting the masses of various states that align well with experimental and lattice QCD data by incorporating constituent masses, hyperfine interactions, and a mass-dependent binding energy term.
This paper presents the design, production, and comprehensive optical characterization of novel light-pulse driver circuits and self-monitoring calibration instruments (both directional pulsers and isotropic P-CAL modules) developed for the Pacific Ocean Neutrino Experiment, demonstrating their high-intensity, nanosecond-scale performance and near-perfect optical isotropy through simulations and experimental validation in air and water.
This paper proposes that the Electron-Ion Collider (EIC) can significantly advance the determination of nuclear weak charge form factors by providing continuous momentum transfer data across a wide range of nuclei, thereby resolving theoretical degeneracies in neutron density distributions that current single-point fixed-target experiments cannot address.
This paper demonstrates that a future 3 TeV muon collider can decisively test the muonphilic dark matter hypothesis, which explains the Galactic Center GeV Excess, by projecting comprehensive exclusion limits across a wide range of mediator masses using four distinct search strategies with a -even mediator.
This paper establishes robust upper bounds on heavy QCD axion lifetimes as low as 0.017 seconds by analyzing Big Bang Nucleosynthesis constraints on neutron-to-proton ratio modifications from hadronic decays, a limit that surpasses projected future CMB bounds and remains largely insensitive to hadronic uncertainties.
Using QCD sum rules, this paper investigates triquark-antitriquark hexaquark configurations to interpret the BESIII-observed and states, finding that two predicted candidates match the experimental masses while offering new predictions for $0^+0^-$ states and analyzing their decay modes.
This paper demonstrates that introducing dark decay channels for sub-GeV heavy neutral leptons fails to evade cosmological constraints, as the resulting increase in extra radiation energy density actually strengthens Big Bang Nucleosynthesis bounds on their mixing angles.
This paper investigates the substructure of quark and gluon jets in photoproduction events at the proposed Electron-Ion Collider using PYTHIA simulations and jet-shape variables, demonstrating the feasibility of distinguishing between these jet types to establish a baseline for future QCD studies.
This paper investigates the energy loss of high-energy partons in anisotropic plasmas within the harmonic approximation, deriving a simple formula for the impact of anisotropy and demonstrating that the resulting medium length dependence exhibits universal limiting attractor characteristics consistent with QCD kinetic theory simulations.
This paper establishes a comprehensive Spin Density Matrix framework for analyzing polarization transfer in the decay chain , demonstrating that the state perfectly preserves the initial polarization in the dominant -wave limit while providing a unified method to quantify -wave deviations and extend these insights to other hadronic and electroweak processes.
This paper demonstrates that simulation-based inference (SBI) is a viable and potentially superior alternative to traditional empirical tuning for determining neutrino interaction model parameters, as it successfully reproduces and slightly improves upon the MicroBooNE collaboration's tuned GENIE configuration while also approximating the NuWro simulation.
This paper extracts the speed of sound in the quark-gluon plasma from ATLAS transverse momentum fluctuation data in ultra-central Pb+Pb collisions by correcting for detection biases and hadronization noise, yielding a result of that aligns perfectly with first-principles lattice QCD calculations.
This paper synthesizes new threshold measurements of production from JLab experiments (007 and CLAS12) with previous GlueX data to confirm a consistent phenomenological determination of the -proton scattering length, while highlighting how upcoming J-PARC measurements will further clarify the systematic trend of vector meson-nucleon interactions predicted by the "young vector meson" hypothesis.
This paper utilizes functional QCD to determine QCD freeze-out conditions by matching theoretical baryon number susceptibilities with experimental proton cumulants, successfully predicting kurtosis values that agree with data and revealing a peak structure near 5 GeV indicative of a critical end point.
This paper reviews the theoretical advantages and experimental progress in studying exotic hadrons associated with the -quark, highlighting the unique capabilities of the Belle, Belle II, and LHCb experiments to explore states like , , and within a more reliable theoretical framework than charmonium-like systems.
This paper proposes that spinning black holes in the Milky Way can act as persistent "scalar sirens" by ejecting light scalar particles via superradiant instability, thereby generating a detectable, high-velocity scalar background that offers a novel, independent probe of isolated black hole populations and scalar field properties.
This paper proposes that high-energy particle decays function as informationally weak measurements of quantum spin, where decay kinematics serve as continuous pointer variables to reconstruct spin states and unify spin tomography with Aharonov-Vaidman measurement theory.
