Probability-based Estimates of the Uncalculated NLO QCD Contribution to the Hadronic -Boson Decay Width
Shu-Heng Yang, Jiang Yan, Xing-Gang Wu +1
The perturbative QCD corrections to the hadronic decay width of the boson are currently known up to next-to-next-to-next-to-next-to-leading order (), whereas th…

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…

Scale-invariant total decay width using the novel method of characteristic operator
Jiang Yan, Xing-Gang Wu, Jian-Ming Shen +2
In this paper, a novel method via using the characteristic operator~(CO) is proposed to extend the applicability of PMC, which is a theoretical generali…
