Calculation of the N to Delta electromagnetic transition matrix element

arXiv:hep-lat/0209074 · doi:10.1016/S0920-5632(03)01571-8

Abstract

We present results on the ratio of electric quadrupole to magnetic dipole amplitudes, $R_{EM}={\cal G}_{E2}/{\cal G}_{M1}$, for the transition $γN to Δ$ from lattice QCD. We consider both the quenched and the 2-flavor theory.
