The $Λ_{b} \to Λ$ transition form factors in perturbative QCD approach

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

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

Next-to-leading order QCD corrections to $B_{c}^{*} \to J / ψ$ 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…
