Hallo Jacco,
Here are my comments.
Cheers & thanks, Niels
---------------------------------------------------------------------------
L.12 Please remove 'for the first time', because it suggests that the other measurements that you list, were not first measurements.
L.85 You train two separate BDT's. Please make clear in the paper that you use a different optimal cut for each BDT. The reader also needs to be able to asses the agreement between the signal yeilds for both samples, and therefore you should mention the value of the selection efficiency for both BDTs.
L.104 Did you consider to update the Bc->JpsiK+ measurement? (http://arxiv.org/pdf/1306.6723.pdf). You might even observe ~10 Bc->Psi(2S)K+ events?
Figs. Please also prepare a plot with _all_ Bc->Jpsipi+ candidates. That will eb very useful for talks. (Then you can decide whether you want to place that in supplementary material, or whether you put the split plots in the supp.material, and the combined plot in the body of the paper.)
L.156 Your statements that you "don't support the theoretical calculations", and "predictions .. are consistent" are too strong, given the uncertainties of the various predictions. Could you prepare a table with predictions and errors, for the supplementary material? (Related to this comment, do you know what changed in arXiv.1209.5859 changing their prediction from 0.42 of before the LHCb measurement, to 0.26 after our publication?)
