Exclusive decays of Xi(QQ') baryons in NRQCD sum rules

Abstract

We perform a detailed study of semileptonic form-factors for the doubly heavy baryons in the framework of three-point NRQCD sum rules. The analyis of spin symmetry relations as well as numerical results on various exclusive decay modes of doubly heavy baryons are given.
