====== 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. |**Francisco Campanario and Thomas Mannel** | | {{preprints:2001:ttp01-34.pdf|PDF}} {{preprints:2001:ttp01-34.ps|PostScript}} | | |
