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)%
