Hi all, I repeated the study vs the integrated purity. ALL: --- http://www.slac.stanford.edu/~daniele/vub/brecoall.eps - pretty nice B0: -- http://www.slac.stanford.edu/~daniele/vub/brecob0.eps - the value increases a lot around 50%. Then it goes down again at high purity. ~ 3-4 sigmas effect Bch: --- http://www.slac.stanford.edu/~daniele/vub/brecobch.eps - fine, I could say I am doing the same plots for the Q1 cut. Daniele
