DOI: 10.1007/jhep03(2025)025
Abstract: We examine the effect of higher-order QCD corrections on the four top-quark production cross section in the 3 lepton decay channel. Top-quark and W gauge-boson decays are included at next-to-leading order in perturbative QCD. The… read more here.

DOI: 10.1103/d7pv-1dqt
Abstract: A recent study shows that incorporating a new term into the thermodynamic potential density, as required by the thermodynamic consistency criterion, can effectively resolve the thermodynamic inconsistency problems of the conventional perturbative QCD model. This… read more here.

DOI: 10.1103/physrevc.107.l052801
Abstract: We construct a physics-agnostic approach to the neutron star (NS) equation of state (EoS) based on a sound speed model, which connects both low-density information from nuclear theory and high-density constraints from perturbative QCD (pQCD).… read more here.

DOI: 10.1103/physrevd.95.014034
Abstract: In this paper, we find, within the framework of perturbative QCD, that in deuteron-deuteron scattering Bose-Einstein correlations, due to production of two-parton showers, induce azimuthal angle correlations with three correlation lengths: the size of the… read more here.

DOI: 10.1103/physrevd.98.013004
Abstract: In the framework of Perturbative QCD (PQCD) approach we study the direct $CP$ asymmetry for the decay channel $\bar{B}_{s}\rightarrow P\pi^+\pi^-$ around the resonance range via the $\rho-\omega$ mixing mechanism (where P refer to pseudoscalar meson).… read more here.
