Lifetimes of doubly heavy baryons

Abstract

We perform a detailed investigation of total lifetimes for the doubly heavy baryons ${\Xi }_{Q{Q}^{\prime }}$, ${\Omega }_{Q{Q}^{\prime }}$ in the framework of operator product expansion over the inverse heavy quark mass, whereas, to estimate matrix elements of operators obtained in OPE, approximations of nonrelativistic QCD are used.
