Hi all, I ran on the new production files and I created the new root files for the fit. This is the usual set fileVubTotal /nfs/farm/babar/AWG7/ISL/tmp/rootfitfiles/sx-allbrecovubmix-right.root fileVubDstar /nfs/farm/babar/AWG7/ISL/tmp/rootfitfiles/sx-dstar-sp3run1-brecovubmix.root fileVubDc /nfs/farm/babar/AWG7/ISL/tmp/rootfitfiles/sx-dc-sp3run1-brecovubmix.root fileVubDstar0 /nfs/farm/babar/AWG7/ISL/tmp/rootfitfiles/sx-dstar0-sp3run1-brecovubmix.root fileVubD0 /nfs/farm/babar/AWG7/ISL/tmp/rootfitfiles/sx-d0-sp3run1-brecovubmix.root fileVcb /nfs/farm/babar/AWG7/ISL/tmp/rootfitfiles/sx-allcocktail-right.root fileData /nfs/farm/babar/AWG7/ISL/tmp/rootfitfiles/sx-alldata.root #fileData /afs/slac.stanford.edu/u/ec/daniele/scra/sx-allgeneric.root fileVubTotal and fileVcb are a proper mixture in order to have the correct ratio(NBch/NBne) (same as data). The number of neutrals is wrong in these files (due to a bug in recoilNtp). Tomorrow I will replace them with the correct ones. These are the results of the fit: MC cocktail: ----------- stat - TOT reco'ed B 1110 K - generated ratioBR 0.01714 param - eps_u = eps_cuts * eps_mx = 0.243 - eps_cuts = 0.343 - eps_mx = 0.707 - (Msl - BGsl)/Msl = 0.9137 - eps_l^u/eps_l^sl = 1.1804 fit results - Msl = 119420 +- 470 => BGsl = 10230 - Mu = 1629 +- 44 - BGu = 1092 +- 11 => Msignal = 538 +- 45 - ratio(BR) = 0.0172 +- 0.0014 http://www.slac.stanford.edu/~daniele/vub/newMCfitresults_nocat.eps * With three shapes (w/o background subtraction) - ratio(BR) = 0.0179 +- 0.0014 http://www.slac.stanford.edu/~daniele/vub/newMCshapefitresults_nocat.eps GENERIC: ------- stat - TOT reco'ed B >400 K - generated ratioBR 0.01107 ? (see next posting) param - same as MC cocktail fit fit results - Msl = 44206 +- 330 => BGsl = 3800 - Mu = 571 +- 29 - BGu = 404 +- 4 => Msignal = 167 +- 30 - ratio(BR) = 0.0145 +- 0.0026 http://www.slac.stanford.edu/~daniele/vub/newgenefitresults_nocat.eps * With three shapes (w/o background subtraction) - ratio(BR) = 0.0143 +- 0.0023 http://www.slac.stanford.edu/~daniele/vub/newgeneshapefitresults_nocat.eps Daniele
