A Primary Study of Heavy Baryons ?Q, ?Q, ?Q and ?Q.

We perform a preliminary study of the and ground-state baryons containing a heavy quark in the framework of the chiral SU(3) quark model. By using the calculus of variations, masses of LQ, SQ, KsQ, OQ, S*Q, Ks*Q and O*Q, where Q means c or b quark, are calculated. By taking reasonable model parameters, the numerical results of established heavy baryons are generally in agreement with the experimental data available, except that those of KsQ are somewhat heavier. For Ob, with undetermined experimental mass and unobserved Ks*b, O*b, reasonable theoretical predictions are obtained. Interactions inside baryons are also discussed. [ABSTRACT FROM AUTHOR]
