B[sup +] [r arrow] D[sub s][sup *+][gamma] and B[sup +] [r arrow] D[sup *+][gamma] as probes of Vub
Technical Report

OSTI ID:5925491
The decays B[sup +] [r arrow] D[sub s][sup *+][gamma] and B[sup +] [r arrow] D[sup *+]gamma can be used for an extraction of [vert bar]Vub[vert bar]. When the b and c quarks are nearly degenerate the rate for these modes can be determined in terms of other observed rates, namely B[anti B] mixing and D[sup *] [r arrow] D[gamma] decay. To this end the authors introduce a novel application of heavy quark and flavor symmetries. Although somewhat unrealistic, this limit provides one with a first estimate of these rates.
