Hi all,
here I show the stat power (BRBR/errBRBR) as a function of the cuts on
mm2 (low cut and high cut) running on cocktail MC (selection phot 6)
qtot=0
http://www.slac.stanford.edu/~daniele/vub/resq0.ps
qtot=-1,0,1
http://www.slac.stanford.edu/~daniele/vub/resq1.ps
Optimal points are in
qtot=0 mm2low=-0.6 Gev^2, mm2high=0.3 GeV^2 (-10% with respect to the
usual range -inf - .5)
qtot=-1,0,1 mm2low=-0.6 Gev^2, mm2high=0.4 GeV^2
In general qtot=0 has an error ~15%-20% lower than the one using
qtot=-1,0,1
