This paper presents a preliminary lattice extraction of the Collins-Soper kernel in Collins' scheme using an auxiliary fermion field representation of the Wilson line, comparing the "ratio" and "double ratio" methods to achieve high statistical precision.
This paper presents the latest hybrid determination of the hadronic vacuum polarisation contribution to the muon magnetic moment by the BMW and DMZ collaborations, achieving 0.45% precision and overturning the theoretical consensus to resolve the long-standing discrepancy with experimental measurements.
This paper demonstrates that in the Minimal Left-Right Symmetric Model with generalized parity, the low-energy Dirac CP-violating phase alone can successfully generate the observed baryon asymmetry of the universe, offering a testable link between neutrino physics and cosmology that depends critically on the neutrino mass ordering and scale.
Using QCD sum rules, this study interprets the resonance as an -wave molecular pentaquark state and calculates its mass and decay properties, finding results consistent with experimental data.
This paper investigates the weak interaction's contribution to the ground-state hyperfine splitting of muonium by calculating amplitudes for one- and two-quantum exchanges mediated by Z and W bosons, as well as deriving one-loop corrections to the photon and Z boson propagators.
This paper presents a complete computation of NNLO helicity and transversity DGLAP splitting functions in both space-like and time-like kinematics, derived from NLO polarized TMD matching coefficients, to enable high-precision NLO cross-section calculations and NLL resummation for future spin physics at the Electron-Ion Collider.
This paper presents a selective overview of theoretical refinements in the gravity sector of the Standard-Model Extension within Riemann-Cartan geometry, focusing on the distinctions and consistency issues between spontaneous and explicit spacetime symmetry breaking to develop a modified framework for investigating explicit breaking and exploring geometries beyond Riemann-Cartan.
This paper employs SU(2) chiral perturbation theory with isospin-breaking effects to derive the QCD -vacuum solution and compute the temperature dependence of topological observables and domain wall tension up to next-to-leading order, revealing distinct monotonic behaviors for different cumulants and providing crucial theoretical insights for axion physics in hot QCD matter.
This paper derives the non-local non-stabiliserness (magic) in gluon and graviton scattering, demonstrating that the helicity basis naturally manifests this quantum resource for standard interactions but fails to do so when new physics operators are introduced.
This paper proposes that inflationary gravitational particle production generates significant late-time dark matter fluctuations, thereby expanding the viable parameter space for four distinct dark matter scenarios (Inert, WIMPy, UFOy, and FIMPy) while remaining consistent with current cosmological constraints.
This paper investigates Lorentz- and CPT-violating contributions to nuclear muon-to-electron conversion within the Standard-Model Extension, deriving the first experimental bounds on relevant quark-lepton operators from SINDRUM II data and exploring potential improvements from future experiments.
This paper demonstrates that precise measurements of the forward-backward asymmetry in events at GeV are feasible at future linear colliders using full ILD simulations, provided that advanced particle identification techniques like Comprehensive PID and cluster counting are employed to optimize charge reconstruction and maximize sensitivity to electroweak and new-physics effects.
This paper develops a quantum kinetic theory for Quantum Chromodynamics that incorporates leading-order collision terms to reproduce the Boltzmann equation at lowest order and predict spin polarization of quarks and gluons at next order, revealing distinct behaviors for vortical versus non-vortical gradients and a mechanism for spin-orbital angular momentum conversion via inelastic collisions.
Using 1.4 years of atmospheric neutrino data from the first six detection units of the KM3NeT/ORCA detector, this study finds no evidence for isotropic Lorentz invariance violation and establishes competitive new limits on relevant coefficients.
This paper develops a unified phenomenological framework for missing-energy searches involving light spin-1 gauge bosons coupled to electroweak-anomalous currents, deriving their effective interactions from minimal anomalon spectra and evaluating constraints from rare flavor and electroweak processes alongside direct searches.
Using high-resolution Lyman- forest data and new Sherwood-Relics simulations, this study presents updated constraints on the isocurvature fraction of post-inflationary axion-like particles, revealing a tentative detection of a non-zero contribution while establishing competitive upper bounds that surpass previous large-scale structure limits.
Using the miniDSE scheme of Dyson-Schwinger equations, this study demonstrates that including dynamical charm quark fluctuations in QCD induces a moderate but noticeable shift of approximately 2–3% to lower chemical potential in the location of the critical endpoint, highlighting the significance of heavy-flavor dynamics in precision studies of the QCD phase structure.
This study utilizes Light-Front Holographic QCD and gauge/string duality to establish a unified framework for extracting quark and gluon distributions and form factors, while demonstrating that the trace anomaly contributes approximately 23% to the proton mass through the analysis of near-threshold production.
Employing the STOchastic LAttice Simulation (STOLAS) code, this study investigates the spatial profiles and topological structures of curvature perturbations in multi-waterfall hybrid inflation models, validating the stochastic-N algorithm while revealing how stochastic noise drives defect reconnection and imposes upper bounds on perturbations in cubic potential scenarios.
The authors construct and classify asymptotically flat dyonic hairy black hole solutions in U(1) gauge-invariant scalar-vector-tensor theories with cubic and quartic interactions, demonstrating that magnetic charge activates specific interaction sectors to generate new solution branches and requires consistency conditions to ensure the field equations remain second-order.
