VertbarVubvertbar from semileptonic decay and b rarrow sγ

Current errors on vertbarVubvertbar are dominated by model dependence. For inclusive decays, the model dependence comes from the Fermi motion of the b quark. By combining the endpoint photon and lepton spectra from the inclusive decays B rarrow Xsγ and B rarrow Xuellbar ν, it is possible to remove this model dependence. We show how to combine these rates including the resummation of the end-point logs at next to leading order. The theoretical errors on vertbarVubvertbar on the order of 10% are possible. We also give a brief discussion on comparing different extractions
