Hoi,
just a few plots, I am not trying to argue in any direction here ...
You can find a comparison of B0/B+ in data/generic/cocktail for the
default selection and |Q| <= 1 in
http://www.slac.stanford.edu/~ursl/talks/070302/main.ps.gz
In data, B0/B+ show the same behavior, the chi2/ndof is a bit worse in
the Q1 case (maybe due to the larger statistics).
In MC, the shapes in generic and cocktail for B0 and B+ are
significantly different in the Q0 case. For Q1, they are in decent
agreement in the enhanced sample, the depleted sample shows the same
behavior like the Q0 case.
The comparison of B0 and B+ separately between data and MC is a bit
worse for Q1 compared to Q0 (most notably in the depl sample, but then
again, the statistics are larger).
Cheers,
--U.
