as usual, please correct for any omissions, mistakes,
misunderstandings...
present: Kerstin, Antonio, Virginia, Concezio, Francesca, Roberto,
Chukwudi
1) S/P systematics (3PDF mes fit): values/errors for S/P as function of
mX were not correct. Now fixed (see separate email).
ACTION ITEM=> repeat the fits and re-evaluate the syst. uncertainty
(Chukwudi)
2) release 18/20 and 2PDF mes fits: results very encouraging. Basically
all PDF parameters left to float, chisquare slightly above 1, albeit on
a low (Run3 only) statistics.
ACTION ITEMS=> evaluate the yields per fb-1 on release-14, -18, -20
data;
compare 2PDF mES fits with release-14 data, possibly on a larger dataset
(Roberto, Antonio, Virginia)
3) unfolding: Kerstin performed 2PDF mES fits by floating all CB
parameters on data and MC with all cuts (release 14) and gets a good
agreement on data. A bit more work needed for Vcb events.
ACTION ITEM=> finalize mES fit parameters (including the ones to be used
on the sample with semileptonic cuts), use them in VVF and evaluate the
impact on the results.
4) CM presentations
- syst. from mES fits (3PDF model): Chukwudi
- experience with new releases and 2PDF model: Roberto
- unfolding (Kerstin)
5) 1/ab workshop: we need to provide an estimate of the ultimate exp.
syst. uncertainties which can be reached. For sure, a better mES fit
procedure will decrease the somewhat conservative associated
uncertainty. Other conservative uncertainties are due to ssbar popping
need to be studied yet.
