$CP$ violation in two-body hadronic ${\Lambda }_b$ decays in the PQCD approach

Jia-Jie Han, Ji-Xin Yu, Ya Li +4

We systematically investigate the $CP$-averaged branching ratios and $CP$ violations (CPVs) for the two-body hadronic decays ${\Lambda }_b\to ph$, where $h$ runs through the mesons ${\pi }^{-}$, $…
