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).…

Study of the $B^{+} \to π^{+} (π^{+} π^{-})$ decay in PQCD Approach

Qin Chang, Lei Yang, Zhi-Tian Zou +1

Based on the fitting results of the LHCb collaboration on the contributions of various intermediate resonances to the $B^{+} \to π^{+} π^{+} π^{-}$ decay, we make systematically calcul…
