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

Simone Romiti (HISKP)

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
