Hoi, all the usual plots split up can be found in http://www.slac.stanford.edu/~ursl/talks/070502/comp.ps.gz The slow pions are clearly visible in the B0 sample. All samples have a (slight) excess at low momenta. In the depl B+ sample, we have that curiously looking region (bins 3,4,5) which is also visible in the B plots, which could be slow pions in data absent in MC. MM2 looks quite fine for B0; if one expected problems from this it would be in the B+ case (both depl and enh). In Qtot, the B0 in data is significantly wider than the MC. Generic has more in Qtot=+1 relative to data. The B+ is relatively well described. In combination, theB+ dominates statistically and to a certain extent, there is also compensation between B0 and B+.
