Hi Wouter,
About 1. : They did not get the question. The GL is trained on background without phis. So it's useless to fight background with phis. Or their sentence is unclear.
I find the reply on the mass fit a bit short. "Therefore we are confident that our signal is well described by a combination of a Crystal Ball and a secondary gaussian that is a model also used in other LHCb analysis." The fact that it was used in analyses where it does not matter not relevant. In this analysis it matters a lot and we'd like to see a study of the mass shape in a sample without background. But looking at the analysis note (p.7) they have a quite good fit to MC with that model.
"The non-resonant part of the signal is not a background and is indeed part of what we report. See the abstract: "29.9±6.4B0s?(K+K-)(K±??) candidates are found in mass windows 746\mevcc<M(K±??)<1046\mevccand 1012\mevcc<M(K+K-)<1026\mevcc" "
well, sure but the title says observation of phiK*.
Cheers,
Patrick
