Calculation of the N to Delta electromagnetic transition matrix element

Abstract

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