Hi all, discussing yesteday's post, Roberto noticed that the fit was not sensible to mm2 cut, since varying the upper limit on mm2, the results were identical. I have investigated this today and discovered a small bug in VVF. The behavior was that even if we didn't specify to cut on Emiss-Pmiss instead of mm2 in the definition of All Cut selection (this is possible using -empm flag in subVirFit.pl), the variable Emiss-Pmiss was actually picked up to make the All Cut selection. I have fixed this and submitted jobs for the three analyses (cut on mm2). As VVF jobs complete I update tables posted in http://www.slac.stanford.edu/~petrella/datafit/data.html (old results are still available at http://www.slac.stanford.edu/~petrella/datafit/data_empm.html) So far only mx analysis has completed. There are encouraging changes since the BRBR values are not so spread, ranging now from 0.0209 for Run 4 to 0.0298 for run 3, where we had 0.0114 for Run 4 up to 0.0333 for Run1-2. Looking at the final mx fit plot, I can see that the vub/vcb ratios in the signal region (Mx<1.55) change too: Run1-2 (mm2) ~1 Run1-2 (emiss-pmiss) ~ 0.83 Run3 (mm2) ~ 1.3 Run3 (emiss-pmiss) ~ 0.5 Run4 (mm2) ~ 0.9 Run4 (emiss-pmiss) ~ 0.25 Run5 (mm2) ~ 0.9 Run5 (emiss-pmiss) ~ 0.45 ciao, Antonio
