Hi all,
I posted on the web page
http://www.slac.stanford.edu/~petrella/mesfits/parameters.html
an update for the yields study in the 3 pdf model mes fit.
In particular I've added numbers for Run3 and Run4 and 3 plots of
Signal/Background ratio for a quick truth-matched/fitted comparison.
We can see that for Run 4 (due to higher statistic?) the fitted S/B are
consistent with truth-matched values, and as already noticed for Run
1-2, the S/B ratio for neutrals is more consistent than for charged.
There is an unexpected behaviour for Run1-2 in charged+neutrals since
the fitted ratio is higher than the truth-matched, while in the charged
sample this ratio is much lower.
I think that even with a fine parameters tuning for each PDF, the
instabilities are not solved at all.
ciao
Antonio
