Sum rules for charmed baryon masses

Abstract

The measured masses of the three charge states of the charmed ${\Sigma }_c$ baryon are found to be in disagreement with a sum rule based on the quark model, but relying on no detailed assumptions about the form of the interaction. This poses a significant problem for the charmed baryon sector of the quark model. Other relations among charmed baryon masses are also discussed.
