Dear all,
I cannot collect the comments, but I have one which may be added. I also hope that somebody will watch for Nikhef papers the coming weeks.
I found it a nice paper.
Line 124 puzzled me with "the yield of the normalization mode N(B0->K*0mu+mu-)=506". In the same sample we are looking for the Ksi, why do we call it a normalization mode? The prompt region is included in the search, as I understood from the abstract with "limits ... for Ksi lifetimes less than 10 ps". There is an earlier mentioning in line 86 of "the normalization sample" defined as what is later shown in Fig.2. So line 124 refers to Fig.2. I now understand.
Second puzzle is why do we normalize to a mumu mass region and not to a specific resonance for which the B0 decay branching ration is known? They would be also separate from the search sample.
More precise formulation might have prevented my misunderstanding here. Maybe avoid mentioning normalization sample/mode ?

Dear all,
No bfys meeting tomorrow. We did not find a volunteer available before the dead line.
I suggest that everybody gives comments to this paper as Cc and that next week somebody combines them for a Nikhef group response uploaded to CDS. An answer may be expected then and should be checked.
As many of us, I will be away from next week and cannot do it.
Best regards, Tjeerd

Hi Tjeerd,
OK, I noted those. Thanks.

I asked the same question. The signal (for zero lifetime) is a subset of the normalisation mode. Here we look for a small peak on top of K*mumu. But that doesn't matter. We measured B->K*mumu including a xi pollution. Of course, if a large signal had been found, a correlation would hve to be determined. But that's not the case. I don't remember now why we did not use the J/psi.
Cheers,
Patrick
The prompt region is included in the search, as I understood from the abstract with "limits ... for Ksi lifetimes less than 10 ps". There is an earlier mentioning in line 86 of "the normalization sample" defined as what is later shown in Fig.2. So line 124 refers to Fig.2. I now understand.
