TTP01-34 Reparametrization Invariance in Inclusive Decays of Heavy Hadrons
Reparametrization invariance is the invariance of the heavy mass limit
under small changes of the heavy-quark four velocity.
We discuss the implications of this invariance for
non-local light cone operators, the matrix elements of which
are relevant for the leading and subleading shape functions describing
differential rates for inclusive heavy-to-light transitions.
