> Riccardo is verifying that the total BR corresponds to 10.4% looking at > MC truth at generator level. > I run at simuboot level over 110K generic Bch and 110K generic B0 with no selection whatever and I counted the number of events with a semileptonic B at generator level. I counted 10.56+/-0.04 % , consistent between electrons and muons, B0 and Bch. In order to get the Br(b->clnu) one needs to divide by 1.0123 in order to subtract the Vub component and therefore Br(b->clnu) in generic =(10.43 +/- 0.04)% Ric
