[Bfys-physics] Nikhef Bfys discussion of draft for PAPER-2013-055, Observation of $\overline{B}^0_{(s)}\to J/\psi f_1(1285)$ decays and measurement of the $f_1(1285)$ mixing angle
Dear all,
I propose to discuss this paper on 13 September Friday morning 10-11 h. It would be nice if somebody volunteered to give a short introduction and collect the comments. Please, let me know as soon as possible. Deadline for our comments on CDS is 17 September.
Best regards, Tjeerd

Hi Tjeerd,
unfortunately I cannot attend the meeting this friday because I'll be in Krakow. I took anyway the advantage of the flight to read this paper and I have a few comments, that you can find attached.
Thanks,

Dear all,
I combined Maurizio's and my comments with the comments made during Friday's meeting, see att. Deadline to submit comments is tomorrow, so I will send the comments tomorrow morning.
Let me know if there is anything missing.
Cheers, Niels
PS. Let me copy the main comments here:
Main comments/questions: ------------------------ L.260/261 [Q: why is the mass veto different for Psi(2S) and X(3872) ?]
L.283 [Q: Do you really mean B0->JpsiK3pi, and not Bs0->JpsiK3pi ? If you really mean B0->JpsiK3pi, then Bs0->JpsiK3pi decays will cause a problem, as they show up under the B0 peak.]
L.301 [Q: How is the fit done? Is it background subtracted? How are the error bars of the open circles obtained? For the Bs0, at large m, a few open circles are higher than the closed ones; how is that possible?]
L.318 [Q: What resonance structures were assumed when calculating these efficiencies?]
L.342: [Q: how is this efficiency calculated?]
Tab.2: [It's pretty curious that most of the systematic errors have the same value of 2.0. While a reader in LHCb could guess where all these numbers are coming from, an external reader may get confused. A brief description on how they are calculated is desireable]
L.369,370 [Q: Some of the phases do not have the +- ambiguity, and others have. Is this intentional?]
L.343+4 [Q: The asymmetric error +0.007 -0.008 is not consistent with the numbers in Tab.2]
L.373 [Q: We missed the logic here. In principle, the tetraquark wavefunction could also contain [ud][ubardbar] , even if the B0s also decays to f1. The Bs0 could decay to f1 through the other two components?]
