Hi all,
on the bottom of the web page
http://www.slac.stanford.edu/~petrella/mesfits/parameters.html
I have posted a table with the study of yields for run 1-2.
These are the yields for the fit with 3 pdfs:
-Background: argus and cutoff crystal ball yields have been summed;
-Signal: only thorsten signal pdf;
-all MC: all the 3 pdfs.
From the truth-matched numbers ("Real" row) we can see that the ratio
S/B is
1.54 for neutral B,
1.87 for charged B
1.71 for charged+neutral
while from the all MC fit we have that S/B is
1.54 for neutral B,
1.37 for charged B,
1.80 for charged+neutral.
so when fitting the charged components on all MC the fit underestimate
the signal, while when fitting the charged+neutral on all MC the fit
overesitmate a little the signal.
