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…
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…
Scheme-independent determination of the QCD running coupling at all scales from jet observables using the principle of maximum conformality and infinite-order scale setting
Leonardo Di Giustino, Stanley J. Brodsky, Philip G. Ratcliffe +2
We present a new approach to determining the strong coupling , over the entire range of validity of perturbative QCD, for scales above and up to the Pl…
A reanalysis of event shape distributions in electron-positron annihilation
Zhu-Yu Ren, Sheng-Quan Wang, Jian-Ming Shen +2
Theoretical calculations for event shape observables are often determined by using the conventional scale setting; i.e. the procedure defined by setting the renormalization scale t…
Self-consistent analysis for the process
Sheng-Quan Wang, Zhu-Yu Ren, Jian-Ming Shen +3
The next-to-next-to-leading-order (NNLO) pQCD predictions for both the decay width and the transition form factor in the process, based on nonrelativistic QC…
