Simone Romiti - Leading Isospin Breaking effects in the spectrum of nucleons and ∆ resonances


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 (d − u)/ΛQCD, coming from the mass difference between u and d quarks.
