Hyperon Radiative Decays in the 1/N_c Expansion
arXiv:hep-ph/0404273 · doi:10.1103/PhysRevD.70.057901
Abstract
Using a recent calculation of transition magnetic moments in the 1/N_c expansion and a calculation showing the suppression of E2/M1 by powers of N_c, we compute the widths for the radiative decays Sigma^* --> Sigma gamma, Sigma^* --> Lambda gamma, and Xi^* --> Xi gamma.
