NNLO QCD Corrections to $D$ -Wave Spin-Singlet Heavy Quarkonia Decay $I^\cdot_{Q 2} \to I^^{3} I^^{3}$ 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 $I^\cdot_{Q 2} \to I^^{3} I^^{3}$ for $D$ -wave spin-singlet heavy quarkonia up to next-to-next-to-leading-order (NNLO) QCD corre…

Updated Determination of Ellis-Jaffe Sum Rules up to $N^{3} LO$ 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…

Determination of $I^\pm_{s} (M_{Z})$ via a high-precision effective coupling $I^\pm_{s}^{g_{1}} (Q)$

Qing Yu, Xing-Gang Wu, Hua Zhou +1

We propose a novel method to determine the strong coupling of quantum chromodynamics (QCD) and fix its running behavior at all scales by using the Bjorken sum rules (BSR). The BSR…
