[Bfys-physics] REMINDER: Comments on CONF-2017-003, Lepton universality test with $B^0\to K^{*0} \ell^+ \ell^-$ decays
Dear b-vissers,
Just a gentle reminder for everyone who has not yet send comments (thank you who did!) of the upcoming deadline (end of today) to pass me the comments for CONF-2017-003 regarding the (really interesting) RK* measurement. Despite that the CONF note will not be published I encourage everyone to read it and comment, the comments will be useful for the upcoming paper and especially physics comments should come as soon as possible.
Tomorrow at the bfys meeting I will give a short overview about the analysis (10min).
Yours, Maarten "the electron man"
Hi Maarten,
I hope I'm still in time to inject my questions.
Cheers, Niels

1) L.392 Deviations from unity from rJpsi is taken as systematic uncertainty. Is this the average deviation of rJpsi, taken as average systematic, or are the deviations taken across phasespace separately (as shown in Fig.160 in the ANA note).
2) L.212 It is not clear from the text if the same BDT is used for signal and normalisation channels.
3) L.266 The background from B->D(Xlnu)lnu is discussed, which only contributes to K*ll and not to K*Jpsi. What amount of background remains after the cut on cos(th_l) ?
4) From the meeting on Tuesday morning 14 March, https://indico.cern.ch/event/622960/ , it appears as if the consistency between the published dG/dq2 is not yet fully understood, due to the use of a different value for BR(B0->JpsiK*0), with/without S-wave correction? This leads to a 10% change in the results shown in the post-unblinding meeting in the afternoon?
