Form Factors for $B_{c}^{*} \to I^\cdot_{c} + l I^½_{l}$ at NLO in QCD

Wei Tao, Ya-Hui Zhao, Li-Ting Wang +2

We present the Non-Relativistic QCD (NRQCD) calculations at the next-to-leading order (NLO) of $I^\pm_{s}$ for $B_{c}^{*} \to I^\cdot_{c}$ vector, axial-vector, tensor and axial-tensor form factors…

The $I^_{b} \to I^$ transition form factors in perturbative QCD approach

Lei Yang, Jia-Jie Han, Qin Chang +1

In this work, we investigate the $I^_{b} \to I^$ transition form factors in the perturbative QCD (PQCD) approach, incorporating higher-twist light-cone distribution amplitudes (LCDAs…

Next-to-leading order QCD corrections to $B_{c}^{*} \to J / I ¨ $ form factors

Qin Chang, Wei Tao, Zhen-Jun Xiao +1

Within the framework of Non-Relativistic Quantum Chromodynamics (NRQCD) factorization, we calculate the next-to-leading order (NLO) perturbative QCD corrections to the form factors…
