Hi all,
Here are my comments:
Dear Patrick and Matt,
Congratulations for that nice new result. It shows the potential of conversions for such studies.
Physics: L.108: why S/sqrt(S+B) while you aim for a limit? Punzi or something similar would have been much more appropriate. Eq.1: You don't say how you treat the factor 2 of B0/B0bar you have wrt to B+. General: Its unclear where the uncertainty on the BF of the normalisation modes enters the computation of the limit. It's not mentioned. Generally, you could give fitted yields?
L.3: the computation (?) of many observables require ... (observables do not require anything) L.22: Please put charges on DD L.25: Is this a Letter? L.31: Please explain better how the converted photons can broaden the mass (?) shape of background. L.33: Say \B=\bd,\Bs here L.34: "fall within the ... signal" sounds like jargon and is not very clear. Which are they? L.39 and many more: CL should be in roman L.61: did you really only use pythia 6? L.78: I presume it's the tracks and not the vertex that is associated to a cluster. Maybe a comma will fix that. L.89: why [] in [jpsigamma] while in L.75 you have (mu)? L.97: You did not say if the largest value is a good or a bad value. L.108: signal events -> signal decays L.112: K*0->K+pi- and not K-pi+. You need to say cc is included. L.120: sig and norm should be roman L.132: which effect? These are statements. I don't see how you turn that into a systematic. L.134: the B mass resolution Fig.2: Bs->J/psigamma should be B->J/psigamma L.146: B+ -> ... L.172: space missing after \piz L.163: kinematics is jargon. Please say what you exactly mean. L.167: systematic uncertainty. L.178: events -> candidates (that's a very nice example of why event should be avoided. All our events are downstream). L.227: You should compare the Bd limit with Babar's here. Fig.4: MC -> simulated. events -> decays [1,6] fix the math to the actual paper title [4] collaboration
Cheers,
Patrick

Dear all,
We have a new paper assigned to comment on. It would be nice if there is a volunteer for Friday 4 September to lead the discussion on this paper. Friday 11 September is "sportdag" and rather close before the deadline on Monday 14.
