Radiative decays of the p-wave charmed heavy baryons

Abstract

The radiative decays of the p-wave charmed heavy baryons to the ground state baryon states are studied in the framework of the light cone QCD sum rules method. Firstly, the transition form factors that describe these transitions are estimated, and then using these form factors the corresponding decay widths are calculated. A comparison of our results on the decay widths with those predicted by the other approaches existing in literature is performed.

“…Ref. [30] studied the Λ b → N * l + l − decay in LCSR and gave the branching ratios Br(Λ b → N * l + l − ) × 10 8 = 4.62 ± 1.85 (l = e), 4.25 ± 1.5 (l = µ), and 0.25 ± 0.09(l = τ ). Ref.…”
