The $\hat{I}{›}_b\to \hat{I}›$ transition form factors in perturbative QCD approach

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

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