Abstract

We carry out a comprehensive investigation on the radiative decays of P-wave bottom baryons using the light-cone sum rule method. We analyze their electromagnetic transitions into ground-state bottom baryons together with a photon. Together with their mass spectra and strong decays investigated in Tan [] and Yang and Chen [], a rather complete quantum chromodynamics (QCD) sum rule study has been done to understand the P-wave singly bottom baryons within the framework of heavy quark effective theory. As summarized in Tables VII and VIII, some P-wave bottom baryons have limited strong decay widths so that their radiative decay widths become non-negligible. We propose to study these excited bottom baryons and their radiative decays in the future Belle-II, BESIII, and LHCb experiments.
