This paper resolves a historical discrepancy in the definition of electric susceptibility in hot QCD by utilizing an exact fermion propagator and improved perturbation theory to demonstrate that the disagreement stems from the choice of thermodynamic ensemble and infrared regularization, while also constructing the susceptibility within a hadron resonance gas model for the low-temperature regime.
This paper presents a systematic NRQCD-based study of meson photoproduction at electron-proton colliders, revealing that while the direct channel dominates, the resolved contribution provides a significant correction in the low- region and grows with collision energy.
This study assesses the validity of the Born-Oppenheimer approximation in potential models for doubly heavy hadrons by benchmarking it against Gaussian expansion method results, revealing that while the approximation is accurate for lighter heavy-quark masses, its performance with different trial wave functions (Slater vs. Gaussian) diverges at higher masses due to the neglect of non-adiabatic corrections.
This paper presents a precision Standard Model analysis and new physics projections for the radiative decay at the LHC, demonstrating its potential to measure the branching ratio with sub-percentage accuracy and to probe axion-like particles and anomalous gauge bosons with enhanced sensitivity down to couplings of .
This paper demonstrates for the first time that neural simulation-based inference (NSBI) can effectively constrain proton parton distribution functions using high-dimensional, unbinned LHC data, achieving significantly improved precision over traditional binned analyses by fully exploiting statistical power and reducing reliance on coarse uncertainty approximations.
This paper presents the first lattice QCD study of ground-state spin- heavy baryons containing charm and bottom quarks using fully relativistic valence quarks on physical HISQ ensembles.
This paper utilizes precision measurements of top-associated photon production ( and ) from the LHC to derive complementary constraints on the electromagnetic and chromomagnetic dipole couplings of vector-like top partners within an effective field theory framework, demonstrating that such observables effectively probe radiative decay scenarios where traditional resonance searches may be less sensitive.
This paper extends the Operator Product Expansion (OPE) algorithm to scalar-QED theory by computing the four-loop anomalous dimension of the fixed-charge operator , along with beta functions and other anomalous dimensions, while introducing a novel loop-integrand construction method to validate the OPE approach for higher-loop renormalization beyond pure scalar theories.
This study presents a comprehensive analysis correlating the highest-energy neutrino event KM3-230213A with gamma-ray bursts by explicitly accounting for angular uncertainties and computing Lorentz invariance violation scales to identify a broader set of potential associations.
This paper presents a novel technique for next-to-leading order accurate simulation of that incorporates finite width effects beyond the Breit-Wigner approximation in resonance- and width-aware parton shower evolution and NLO matching, offering a publicly available tool for future electron-positron collider studies.
