Sažetak:
The problem of the Xic+ lifetime is considered in the framework of heavy-quark expansion and SU(3)flavor symmetry. The lifetime of Xic+ is expressed in terms of measurable inclusive quantities of the other two charmed baryons belonging to the same SU(3)flavor multiplet in a model-independent way. In such a treatment, inclusive decay rates of singly Cabibbo suppressed decay modes have a prominent role. An analogous approach is applied to the multiplet of charmed mesons yielding interesting predictions on Ds+ properties. The results obtained indicate that a more precise measurement of inclusive decay quantities of some charmed hadrons (such as Lambdac+) that are more amenable to experiment can contribute significantly to our understanding of decay properties of other charmed hadrons (such as Xic+) where discrepancies or ambiguities exist.
