Hi,
here are a couple of plots showing the mm2 distribution for the
resonant signal decays:

http://www.slac.stanford.edu/~menges/Vub/Fitter.new/mm2_zoom.eps
The different final states are, as expected, peaking around zero but not
very sharp. A tight cut will not help very much to separate good
reconstructed resonances from not so good reconstructed ones..
Cheers,
Wolfgang
