My comments on this paper. Btw, just as Patrick I also do not understand l.184-185. It is a valid question to ask.
General:
Maybe I missed it, but I do not fully understand why the analysis is split in 7 and 8 TeV. In particular concerning the choice of the binning and multivariate optimisation.
Specific:
-l.2: “An observation of …”. That is better than “Any observation”. You actually say later that E-40 is still within the SM (w/ massive nu).
-l.14: Write “\taum” instead of “tau”. To be consistent with the rest of the text.
-l.13-25: This paragraph contains a lot of “LHCb”. By the end the reader surely knows who did the measurement. Suggest to remove the occurrences in l.18 and l.21.
-l.18: Add comma after CL.
-l.22: remove hyphen in cross section. Although the EB guidelines may give another suggestion, this word is not hyphenised in any dictionary (included those suggested by the EB).
-l.25: Add “at 7 TeV.” at the end of this sentence.
-l.31+94: “expected mass resolution”. This sounds a bit like we are still trying to understand our detector. But in reality, we should talk about the mass resolution of our detector (which of course depends on the momenta of the final state particles and
the Q-value). Not about mass resolution of a specific decay. Suggest “intrinsic mass resolution” or similar.
-l.112: "An ensemble selected … is used.” This is too much information in one sentence. Better to explain a little bit more. Ensemble selection is new to me. If you keep using it like this, please add a hyphen “ensemble-selected”.
-l.127+134: You say that the PDF is calibrated. But which PDF? This is not mentioned before. Don’t you mean that the classifiers are calibrated such that they return a probability or likelihood? In that case the mentioning of likelihood in l.136 also makes
sense (now it does not).
-l.152: why meson. Shouldn’t it be heavy hadron instead, to not exclude baryons?
-l.154: “There is a large number of …”. Not are. Number is singular!
-l.217: “estimates”. Not estimations.
-l.230: “In summary, the previous LHCb limits …”
-l.231: Remove “3.0 fb-1 of”. Jargon.
-l.232: “The presented limits”
-l.233: “B-factories”. B in italic.
-l.233: allow -> give
-l.234: Remove “to be placed”

Dear all,
We have a new paper for comments before 2 September.
I propose to discuss it at Friday morning 29 August.
It would be nice to have a volunteer to introduce this
paper and to collect the comments.
Best regards,
Tjeerd
