Description
It is shown that, in the bound state picture, the Λc(2593)→Λcγ and Λc(2625)→Λcγ decays are severely suppressed. On the other hand, for their bottom counterparts, which are predicted to have masses of 5900 and 5926 MeV, respectively, they may have significant radiative branching ratios. The Λb(5926)→Λbγ mode possibly dominates over the strong decay mode, while the Λb(5900) resonance lies below the strong decay threshold and can only decay radiatively. The isospin allowed ΛQ**→ΣQγ mode is expected to be small. copyright 1996 The American Physical Society
