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 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...

Supersymmetric gauge potentials in multiphoton transition of atoms and squeezed-vacuum-state driven supersymmetric “isospin” evolution
Energy spectrum of a multiphoton-transition Jaynes-Cummings model with supersymmetry breaking and some relevant topics such as multiphoton dark state (photon-atom dark-state polariton) and multiphoton coherent...

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...

The dark-baryonic matter mass relation for observational verification in Verlinde’s emergent gravity
Recently, a new interesting idea of origin of gravity has been developed by Verlinde. In this scheme of emergent gravity, where horizon entropy, microscopic de Sitter states and relevant contribution to gravit...

Iterative and accurate determination of small angle X-ray scattering background
X-ray scattering is widely used in material structural characterizations. The weak scattering nature, however, makes it susceptible to background noise and can consequently render the final results unreliable....

A gravitational gauge field theory based on Stephenson–Kilmister–Yang gravitation with scalar and spinor fields as gravitating matter sources
A gravitational gauge theory with a spin–affine connection (Lorentz connection) as a rotational gauge potential (fundamental dynamical variable) is suggested for reformulating the theory of Stephenson–Kilmister–Y...

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, ...
