Hi, > our contribution is to be found in: > > http://www.slac.stanford.edu/~petrella/thecomp.html > http://www.slac.stanford.edu/~sacco/meetings/2005-04-12/newrew.html unfortunately I could not attend the meeting (I was on a plane). The results look very nice and the level of the comparison is good. I have a couple of comments: - when you compare the value of the branching ratios take into account that the samples (CM1-CM2) are quite uncorrelated. Francesco made few tests on this (see http://www.slac.stanford.edu/~gallof/exclVub/Breco-overlap.html ) and the overlap is around 60%. This is due just to the redefinition of the breco modes and to the reprocessing and differences in skimming - the data-MC comparison looks very nice. Only issue I have is about the mx comparison for the depleted sample. I see the presence of tails that in CM1 was not there. It is striking without cuts where you can see a huge bin at zero. Do we understand that? It could be that we still have some looser selection (it could be on neutrals). Let me know Daniele
