Isospin Mass Splittings of Baryons in Potential Models
Kalman Varga, Marco Genovese, Jean-Marc Richard, Bernard Silvestre-Brac
Abstract
We discuss the isospin-breaking mass differences among baryons, with particular attention in the charm sector to the Σc+-Σc0, Σc++-Σc0, and Ξc+-Ξc0 splittings. Simple potential models cannot accommodate the trend of the available data on charmed baryons. More precise measurements would offer the possibility of testing how well potential models describe the non-perturbative limit of QCD.
