This paper generalizes the Semkow summing correction formalism into matrix and partitioned frameworks to analyze 180-degree and gated coincidence events in the GRIFFIN spectrometer, ultimately demonstrating that the statistical deviations inherent in these corrections bound the sufficient measurability of true coincidence summing.
This review examines a decade of theoretical and experimental advancements in muon physics, highlighting global efforts to enhance sensitivity in studying muon decays, magnetic and electric dipole moments, and charged lepton flavor violation to probe New Physics scenarios and guide future facility proposals.
This paper establishes a new benchmark for heavy-quark TMD resummation at the LHC by developing a framework that combines SCET and HQET to achieve NNLL' accuracy for the azimuthal decorrelation of boosted top quark pairs, a feat made possible by the first extraction of the two-loop ultra-collinear function.
This Geant4 simulation study validates the ePIC experiment's dRICH detector design by demonstrating that the n=1.026 aerogel radiator significantly enhances high-momentum -K separation while quantifying the moderate impact of SiPM dark noise on performance thresholds.
This paper investigates how the reflectivity and phase shift of a storage bottle wall influence the sensitivity of ultracold neutron experiments searching for neutron-antineutron oscillations, highlighting the critical role of optimizing the antineutron pseudopotential and proposing methods to determine it.
This paper proposes that ultra-peripheral ion collisions generate entangled multi-particle states through shared photon polarization, leading to distinct azimuthal angular correlations that differ significantly between classical and quantum predictions and offer new avenues for testing multi-particle entanglement.
This Letter presents a consistent matching of short-distance contributions and hadronic matrix elements for pion decay and decays beyond leading-logarithmic accuracy using recent lattice QCD results, thereby significantly reducing theoretical uncertainties to enable more precise future determinations of and the muon's anomalous magnetic moment.
This study presents the first exploratory lattice QCD calculation of nucleon unpolarized, helicity, and transversity parton distribution functions using boosted correlators in the Coulomb gauge, demonstrating that the method yields results compatible with global analyses for valence-quark distributions while highlighting the need to address excited-state contamination in full-quark-channel extractions.
This paper derives the complete set of positivity bounds for leading-twist parton distribution functions of spin-3/2 hadrons by generalizing the Soffer bound through the analysis of antiparton-hadron scattering amplitudes and the positive definiteness of the scattering amplitude matrix.
This paper reports a systematic measurement of elliptic flow for strange and multi-strange hadrons in isobar collisions at GeV, revealing approximate constituent quark scaling indicative of partonic collectivity and observing a 2% deviation in flow ratios between Ru+Ru and Zr+Zr collisions that highlights differences in their nuclear structure and deformation.
