Description
The inclusion of isospin-breaking corrections arising from electromagnetic interactions and the up–down quark mass difference has become timely in modern lattice QCD calculations, as the precision of many observables has reached the percent level. In this context, the RM123 method has played a pivotal role in recent years. In this work, we apply this framework to the study of baryon mass splittings. In particular, we present preliminary results for the mass splittings within the spin-1/2 and spin-3/2 baryon isomultiplets, obtained using twisted-mass ensembles tuned close to the isospin-symmetric point defined according to the Edinburgh/FLAG consensus.
