Hi Marcel,

My comments on the Z boson paper:

General:
- Following the remark by Patrick, it was not clear to me that the W boson cross section measurements were redone. It this is true, this should be made clear in the text.
- Section 4.1 discusses the efficiency corrections. They are measured with a tag-and-probe technique. However, it is not mentioned in the text which resonances are used for this. I presume it is the Z resonance itself, but this information is missing. Secondly, I wonder how correlated the uncertainties of these tag-and-probe methods are, since this is using the same data sample. Take e.g. the muon ID. If you calculate the muon ID efficiency from the same Z sample, you could have just as well not applied this cut. Actually, this overestimate the true uncertainty. Or, do you assume the same efficiency for both muon charges? Even then there is still some correlation. In case you have carefully treated all these correlations, please mention this in the text.
- Section 4.4 explains the unfolding due to the finite resolution of pt and phi*. For my understanding, is this really such a large effect? Could you give the reader an idea for how large this effect is?
- The section “Conclusions” reads as an abstract. There is no discussion on the result. Consider to remove this section, except for the last sentence, or rewrite this section.
- In the acknowledgement there is a statement that Ward provided some MC generator predictions. First, in other papers, any deviation from the standard acknowledgements is put at the start. Second, why is it needed to mention this, when he has been referenced already? Third, the current text is just a statement, rather that thanking him. Please make clear why you thank him and that you thank him.

Textual:
- Several places: "data set” is two words.
- Several places: TeV is not in the LHCb symbol style.
- L15: “the latter data”. This is confusing, since you really mean the data set. Data can be confused with the "Z boson data”. Suggest to change it to “the 1 fb-1 data set”.
- L18: “an update to the analysis” -> “an update of the analysis"
- L22: Add a digit to the lower eta range: 2.0
- L24: Add the reference at the end (i.e. after “as”)
- L26: “acop” should be in roman font (just as in Eq.2).
- L28: “combined with previously” -> “combined with the previously”
- L28: Add again the reference “[3]” after “W bosons”.
- L30: Remove “complete”
- L32-36: I don’t think this paragraph with the description of the following sections is really needed. This is not such a long paper.
- L48: Remove the extra space before GeB (note that this requires changes the symbol definition).
- L61: Why do you "explain” the Van der Meer scan, but not the beam-gas imaging? Suggest to either remove the VDM explanation (“where colliding beams…profile”) or add a similar explanation after the beam-gas method.
- L93: Z should be italic.
- L94: Abbreviate Fig. 1.
- Fig.1: Use larger fonts for all text (axis titles, axis labels etc). Events should start with capital.
- L96: Nouns missing. Add “decays, and” after Z->tautau. Add “production” after W+W-.
- L100: “the techniques in [6]” -> "the techniques from Ref. [6]"
- L102: “in Ref. [6]" 
- L104: Add “decays” after Z->tautau
- L131: Combine “Refs.[1,6]"
- L132: Add “the” in “both the tag and probe…”
- L145: Add hyphen in “single-muon trigger”
- L160: Put "GEC" in roman font
- L206: {\boldmath \Z} in the title.
- L224: “Fig. 5”
- L266: “can be used to improve the determination of the PDFs.” It would be nice to add a reference here.
- App C: Missing references here. No reference is given for these predictions and data points.
- References: Make sure that “collaboration” is always in lowercase. Put nouns in titles to lowercase everywhere (e.g. in Refs.[37-42]).
- Ref.[9]: is now published. Use the latest LHCb-PAPER.bib.

Cheers
Jeroen

Dear all,

We have a new paper to discuss by Nikhef.
I propose it for next bfys meeting on Friday 27 March.
Does somebody volunteer to introduce it?

Best regards,
 Tjeerd
