Abstract

A diquark model is used to investigate singlecharmed baryons. In this model, baryon is composed of two diquarks and an antiquark. Masses of lowest lying states with JP=1/2± are obtained. Baryons in our results are as heavy as other theoretic predictions and we suggest that the fivequark components should be considered in any threequark model for studying the charmed baryons.
