Abstract
The inclusive decays of doubly heavy baryons are studied on the basis of the operator-productexpansion method. The lifetimes of these particles are calculated, and the dependence of the respective theoretical predictions on the quark masses is studied. Theoretical uncertainties that arise in the predictions of the widths with respect to different channels and of the total lifetimes owing to the aforementioned dependence are also estimated.
