The heavy flavor conserving hadronic weak decay of the ground-state bottom baryons

Abstract

In this work the heavy flavor conserving (HFC) hadronic weak decays of bottom baryons are studied in the framework of the nonrelativistic constituent quark model (NRCQM). We show that the pole terms play an indispensable role in the description of the branching ratio of $\hat{I}{ž}_b^{-}\to \hat{I}{›}_b^0\ddot{I}{€}^{-}$. With the pole terms included we can make reliable predictions for $\hat{I}{ž}_b^0\to \hat{I}{›}_b^0\ddot{I}{€}^0$. A combined study of the HFC hadronic weak decays allows us to make a reasonable prediction for $\hat{I}{\text{c◯}}_b^{-}\to \hat{I}{ž}_b^{-(0)}\ddot{I}{€}^{0(-)}$, which can be searched for at LHCb and Belle-II experiments.
