Hi all,
I repeated the comparison data-generic MC with a different selection on
neutrals and charged tracks.
GTVL = Good track very loose
GPL = Good photon loose
the table of plots is in
http://www.slac.stanford.edu/~daniele/vub/GTVL_GPL.html
and you can compare with the first column in the table in the page
http://www.slac.stanford.edu/~daniele/vub/disagree.html
for the usual selction (charged tracks + Alessio's neutral selection)
What I notice is the following
mm2: large improvement after lepton cut
small improvement after all cuts
mxhad: still bad after lepton cut (MC shift, data unchanged)
- after all cuts (I have to fix this plot)
mxhadfit: level of comparison almost unchanged
As far as these three variables are concerned it seems that the data do
not change so much while the MC has a dramatic change (between the
original and the new selection)
BUT I see very bad comparison in the total number of NEUTRALS nad CHARGED
TRACKS. Again MC change dramatically.
The total charge plot is pretty different than before. Now the bin at
zero has more entries in data (before was in MC).
Urs, do you confirm my observations?
Daniele
