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.
