NNLO QCD Corrections to -Wave Spin-Singlet Heavy Quarkonia Decay via the Principle of Maximum Conformality
Hua Zhou, Xing-Gang Wu, Qing Yu +1
In this paper, we perform a comprehensive study of the decay process for -wave spin-singlet heavy quarkonia up to next-to-next-to-leading-order (NNLO) QCD corre…
New Determinations of the Charm and Bottom Quark Masses Using QCD Quarkonium Sum Rules
Qing Yu, Hua Zhou, Xing-Gang Wu
We reanalyze the perturbative QCD (pQCD) corrections to quarkonium QCD sum rules and extract the heavy quark masses (). At present, the…
Analysis of the Pion Electromagnetic Form Factor with Next-to-Next-to-Leading Order QCD Corrections
Sheng-Quan Wang, Zuo-Fen Liao, Jian-Ming Shen +5
NNLO QCD corrections for the pion electromagnetic form factor at large momentum transfer have been recently performed in [Phys. Rev. Lett. 132, 201901 (2024); Phys. Rev. Lett. 134,…
Analysis of up to Next-to-Next-to-Leading Order QCD Corrections
Wen-Yuan Li, Sheng-Quan Wang, Jian-Ming Shen +3
The rare exclusive decay of the Higgs boson is an important channel for measuring the Yukawa coupling of the charm quark. In this article, we analyze the process b…
Determination of using Bayesian analysis of the semileptonic decay width with four-loop QCD corrections
Wang Li, Xing-Gang Wu, Hua Zhou +1
The Cabibbo-Kobayashi-Maskawa matrix element is an important Standard Model parameter, whose value can be determined by using the semi-leptonic decay $B\rightarrow D…
Updated Determination of Ellis-Jaffe Sum Rules up to QCD corrections
Hua Zhou, Qing Yu, Xing-Gang Wu
In this paper, we explore the properties of the Ellis-Jaffe Sum Rule (EJSR) by employing the Principle of Maximum Conformality (PMC) approach to address its perturbative part up to…
