Open AccessNovel method to reliably determine the QCD coupling from Ruds measurements and its effects to muon g − 2 and \( \alpha \left({M}_Z^2\right) \) within the tau-charm energy region
We present a novel method for precisely determining the QCD running coupling from Ruds measurements in electron-positron annihilation. When calculating the fixed-order perturbative QCD (pQCD) approximant of Ruds,...

Open AccessExtending the predictive power of perturbative QCD using the principle of maximum conformality and the Bayesian analysis
In addition to the evaluation of high-order loop contributions, the precision and predictive power of perturbative QCD (pQCD) predictions depends on two important issues: (1) how to achieve a reliable, converg...

Open AccessQCD improved top-quark decay at next-to-next-to-leading order
We analyse the top-quark decay at the next-to-next-to-leading order (NNLO) in QCD by using the Principle of Maximum Conformality (PMC) which provides a systematic way to eliminate renormalization scheme and sc...

Open AccessNew analyses of event shape observables in electron-positron annihilation and the determination of αs running behavior in perturbative domain
In this paper, we give comprehensive analyses for event shape observables in electron-positron annihilation by using the Principle of Maximum Conformality (PMC) which is a rigorous scale-setting method to elim...

Open AccessRevisiting the bottom quark forward–backward asymmetry \(A_\mathrm{{FB}}\) in electron–positron collisions
The bottom quark forward–backward asymmetry \(A_\mathrm{{FB}}\)AFB is a key observable in electron–positron collisions at the \(Z^{0}\)Z0 peak. In this paper, we employ the Principle of Maximum Conformality (PMC)...

Open Access\(\bar{B}_s \rightarrow f_0(980)\) form factors and the width effect from light-cone sum rules
In this paper we calculate the \(\bar{B}_s \rightarrow f_0(980)\)B¯s→f0(980) form factors from light-cone sum rules with B meson DAs. With adopting the quark–antiquark configuration of light scalar mesons, the hi...

Open AccessExtending the predictive power of perturbative QCD
The predictive power of perturbative QCD (pQCD) depends on two important issues: (1) how to eliminate the renormalization scheme-and-scale ambiguities at fixed order, and (2) how to reliably estimate the contr...

Open AccessRenormalization group improved pQCD prediction for Υ(1S) leptonic decay
The complete next-to-next-to-next-to-leading order short-distance and bound-state QCD corrections to Υ(1S) leptonic decay rate Γ(Υ(1S) → ℓ+ℓ−) has been finished by Beneke et al. [8]. Based on those improvements, ...

Open AccessThe Higgs boson inclusive decay channels \(H \rightarrow b\bar{b}\) and \(H \rightarrow gg\) up to four-loop level
The principle of maximum conformality (PMC) has been suggested to eliminate the renormalization scheme and renormalization scale uncertainties, which are unavoidable for the conventional scale setting and are ...

Reanalysis of the BFKL Pomeron at the next-to-leading logarithmic accuracy
We apply the principle of maximum conformality (PMC) to the Balitsky-Fadin-Kuraev-Lipatov (BFKL) Pomeron intercept at the next-to-leading logarithmic (NLL) accuracy. The PMC eliminates the conventional renorma...
