Lifetimes of doubly heavy baryons

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

We perform a detailed investigation of total lifetimes for the doubly heavy baryons ΞQQ\Xi_{QQ'}, ΩQQ\Omega_{QQ'} 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.
