Study of charm and beauty mass spectra, semileptonic decays of $B_{(s, c)}$ and $B_{c} \to J / ψ (η_{c}) + P (V)$ in a phenomenological potential model

S. Rahmani, W. C. Luo, C. W. Xiao

Using a non-relativistic potential model, we obtain the mass spectra, leptonic decay constants, and parameters of the Isgur-Wise function for the beauty and charm mesons. With the…

Tension between $e^{+} e^{-} \to η π^{-} π^{+}$ and $τ^{-} \to η π^{-} π^{0} ν_{τ}$ data and non-standard interactions

Saray Arteaga, Ling-Yun Dai, Adolfo Guevara +1

We show the discrepancy between the isospin-rotated $e^{+} e^{-} \to η π^{-} π^{+}$ cross-section -- measured by various collaborations -- and the Belle $τ^{-} \to η π^{-} π^{0} ν_{τ}$ spectrum, which canno…

Determination of pion distribution amplitudes from the electromagnetic form factor with the data-driven dispersion relation

Jian Chai, Shan Cheng, Jun Hua

We study the pion electromagnetic form factor in the modulus squared dispersion relation, and do the model independent extraction of the most important nonperturbative parameters i…

Precise perturbative predictions from fixed-order calculations

Jiang Yan, Zhi-Fei Wu, Jian-Ming Shen +1

The intrinsic conformality is a general property of the renormalizable gauge theory, which ensures the scale-invariance of a fixed-order series at each perturbative order. Followin…

Structure around $p p ˉ$ threshold in $J / ψ$ radiative decays

Qin-He Yang, Di Guo, Ling-Yun Dai

In this paper, we study the structure around the $p p ˉ$ threshold that appears in $η^{'} π^{+} π^{-}$ , $3 (π^{+} π^{-})$ and $K_{S}^{0} K_{S}^{0} η$ invariant mass spectra in the processes of relevant…

Extending the Predictive Power of Perturbative QCD Using the Principle of Maximum Conformality and Bayesian Analysis

Jian-Ming Shen, Zhi-Jian Zhou, Sheng-Quan Wang +4

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 t…
