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…
EEXICC: An event generator for doubly heavy baryon production at colliders
Hong-Tai Li, Xu-Chang Zheng, Xing-Gang Wu +2
We present EEXICC, a Monte Carlo event generator designed to simulate the production of doubly heavy baryons (, , and ) via annihilation. Based…
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…
A new method for estimating unknown one-order higher QCD corrections to the perturbative series using the linear regression through the origin
Zhi-Fei Wu, Xing-Gang Wu, Jiang Yan +2
It is generally believed that the QCD theory is the fundamental theory for strong interactions. Due to the asymptotic freedom at the short distances, after proper factorization, on…
Renormalization and Factorization Scale-Invariant Predictions for the Higgs Rare Decay via the Principle of Maximum Conformality
Qi-Sha Ran, Xing-Gang Wu, Jiang Yan +2
We investigate the \(J/Ï\) direct production mechanism in the rare exclusive Higgs decay \(H\to J/Ï+γ\) within nonrelativistic QCD (NRQCD), which provides a clean probe for extr…
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…
