The CJ26 global QCD analysis presents a new set of NLO parton distribution functions by incorporating the complete suite of JLab 6 GeV and the first published 12 GeV data to uniquely disentangle higher-twist effects from off-shell nucleon corrections, thereby significantly reducing uncertainties in the large- structure function and valence quark ratios.
This paper demonstrates that relativistic heavy-ion collisions, simulated via the PHSD transport approach and CATS correlation analysis, provide a superior environment compared to proton-proton collisions for studying charmed-meson interactions and probing exotic hadronic states through femtoscopic correlations due to enhanced charm production, reduced relative momenta, and suppressed initial-state effects.
This paper proposes an RG-improved effective field theory framework that reorganizes short-range dynamics by integrating out meson-exchange degrees of freedom, successfully describing the deeply bound dibaryon as a bound state with a binding energy consistent with experimental data and large- expectations.
By employing resummation schemes to derive analytical rates for radiative energy loss in evolving backgrounds, this paper demonstrates that strong jet quenching requires a medium equilibration time longer than its mean free path and reveals that initial-state evolution with weak jet coupling typically enhances azimuthal asymmetry for a given suppression factor.
This paper classifies physical operators up to dimension six in the most general bosonic effective gauge theory and computes their complete one-loop anomalous dimensions using on-shell and geometric techniques, providing a universal framework that is validated against and extends existing results for the Standard Model Effective Field Theory and axion-like particle models.
This paper introduces a new interface between PineAPPL and MATRIX that enables the calculation of fully differential cross-section interpolation grids at NNLO QCD and NLO EW accuracy, allowing for efficient predictions with arbitrary parton distribution functions and facilitating global PDF analyses without relying on approximate K-factors.
This paper reviews recent achievements and future prospects of collider neutrino experiments, particularly at the Forward Physics Facility, highlighting their role in measuring high-energy neutrino interactions, exploring new physics scenarios, and reducing systematic uncertainties to advance both particle physics and astrophysical neutrino observations.
This paper investigates a minimal extension of the Standard Model with a local gauge symmetry and right-handed neutrinos, demonstrating that the resulting first-order phase transition produces a stochastic gravitational wave spectrum detectable by future experiments while simultaneously explaining neutrino masses and baryogenesis through thermal leptogenesis.
This study utilizes the HYDJET++ model to investigate how nuclear deformation parameters (, ) and surface diffuseness () influence charged hadron multiplicity and elliptic flow in symmetric isobaric and collisions at GeV, revealing distinct dependencies on collision geometry (tip-tip vs. body-body) that are compared with STAR experimental data.
This paper proposes that the fundamental gauge and diffeomorphism invariance of nature arises from a dual quantum information principle requiring scattering amplitudes to maximize entanglement while minimizing the generation of non-Clifford "magic" resources.
