Description

We present a lattice calculation of the leading corrections to the masses of nucleons and Δ resonances. These are obtained in QCD+QED at 1st order in the Isospin Breaking parameters αEM , the electromagnetic coupling, and (m̂d − m̂u)/ΛQCD, coming from the mass difference between u and d quarks.
