Isospin splitting in heavy baryons and mesons
R. E. Cutkosky, Paul Geiger
Abstract
A recent general analysis of light-baryon isospin splittings is updated and extended to charmed baryons. The measured Σc and Ξc splittings stand out as being difficult to understand in terms of two-body forces alone. We also discuss heavy-light mesons; though the framework here is necessarily less general, we nevertheless obtain some predictions that are not strongly model-dependent.
