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

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
