Pion Photoproduction Amplitude Relations in the 1/N_c Expansion
Thomas D. Cohen, Daniel C. Dakin, Richard F. Lebed +1
We derive expressions for pion photoproduction amplitudes in the 1/N_c expansion of QCD, and obtain linear relations directly from this expansion that relate electromagnetic multip…

Hyperon Radiative Decays in the 1/N_c Expansion
Richard F. Lebed, Daniel R. Martin
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…

Complete Analysis of Baryon Magnetic Moments in 1/N_c
Richard F. Lebed, Daniel R. Martin
We generate a complete basis of magnetic moment operators for the N_c = 3 ground-state baryons in the 1/N_c expansion, and compute and tabulate all associated matrix elements. We t…
