Radiative decays of <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>P</mml:mi></mml:math>-wave bottom baryons from light-cone sum rules

We carry out a comprehensive investigation on the radiative decays of <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:mi>P</a:mi></a:math>-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 <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" display="inline"><c:mi>P</c:mi></c:math>-wave singly bottom baryons within the framework of heavy quark effective theory. As summarized in Tables VII and VIII, some <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" display="inline"><e:mi>P</e:mi></e:math>-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.
