Hi all,

 I produced the plots that show the resolution as a function of mm2 both
for mxhad and mxhadfit for the new selection.

 b->clnu

 b->ulnu

 They are produced on the cocktail MC. The cut applied are

 - one lepton
 - pcms > 1
 - |mm2| < 1


 I did the same as a function of the true Mx

 b->clnu

 b->ulnu

 If I compare with the ones in the BAD (page 24-25) I notice that:

 1) now the Mxhad resolution is better
 2) the benifit from the kinematic fit is lower
 3) a bias is present for b->clnu (~100 MeV). Before (BAD) the mean was
    always unbiases


 Do we have to train again the kinematic fit with the new selection
track and neutral selection?


 BTW, Oliver, may you confirm that I applied the same cuts used to produce
the plots in the BAD and that you are plotting mean and RMS and not the
result of a gaussian fit?
