Scientific paper

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