M1 transitions in the MIT bag model

Abstract

We investigate, in the MIT bag model, the $M$ transitions of low-lying hadrons. We perform the following calculations: (1) We recompute 32 hadron masses with a choice of bag parameters designed to give the correct values for the proton magnetic moment, ${\mu }_p$, and several masses, $M_{\rho }$, $M_{\omega }$, $M_{\Delta }$, $M_{\Omega }$, and $M_D$; (2) we compute $\eta$, ${\eta }^{ ,}$, ${\eta }_c$ mixing in an untrustworthy approximation; and (3) we compute the widths for 38 $M$1 transitions.
