DOI: 10.1007/jhep09(2018)167

Abstract: A bstractWe determine the charm and bottom quark masses using the N3LO perturbative expression of the ground state (pseudoscalar) energy of the bottomonium, charmonium and Bc systems: the ηb, ηc and Bc masses. We work… read more here.

DOI: 10.1088/1674-1137/abcd2c

Abstract: Measuring the fermion Yukawa coupling constants is important for understanding the origin of the fermion masses and their relationship with spontaneously electroweak symmetry breaking. In contrast, some new physics (NP) models change the Lorentz structure… read more here.

recommendations! Published in 2024 at "Physical Review D"

DOI: 10.1103/fhkc-kfhr

Abstract: It has been shown that entanglement and Bell nonlocality, which are key concepts in Quantum Mechanics, can be probed in high-energy colliders via processes of fundamental particle scattering. In fact, the ATLAS and CMS collaborations… read more here.

DOI: 10.1103/physrevd.102.032007

Abstract: Ratios of cross sections, $\sigma$(Z+c jets)/$\sigma$(Z+jets), $\sigma$(Z+b jets)/$\sigma$(Z+jets), and $\sigma$(Z+c jets)/$\sigma$(Z+b jets) in the associated production of a Z boson with at least one charm or bottom quark jet are measured in proton-proton collisions at… read more here.

DOI: 10.1103/physrevd.111.076008

Abstract: We examine the behavior of singular leading and subleading logarithms, commonly referred to as the soft-virtual (SV) and next-to-soft-virtual (NSV) terms, in the production of the Higgs boson via the bottom quark annihilation channel. We… read more here.
