I paste here my comments. Please let me know if someone else was looking at it, so we can merge comments. Else I'll submit tomorrow.

Dear Xabier, Cédric, Murilo,

Here are my comments on the paper.

L.2: say why it is interesting. L.3: spell out SM. events -> cross-sections (or production) L:5: large momentum fraction of what? L.8: suggest to add some space between + and bb (or cc) L.22-35: This is too detailed for an introduction. At this level the reader does not want to know which flavour of BDT you used. This section could be moved to a separate section 3 and shortened here. L.23: extract -> determine L.33: cross-sections L.44: (natural units are used with c=1) L.76: The same L.78: max in roman L.104: I fail to understand this sentence L.111: I suggest to apply my suggestion to the CONF of using \ell to mean e or mu L.135: Fig. 1 L.142: is is L.171: extraction -> determination L.172. Why binned? And a fit to what? L.175: considering -> assuming that L.178: to the expected yields assuming the SM L.184: Wilks' Table 1: just -> only Fig.2: remove "data" L.190-191: this is not a sentence L.193: "matched with a beauty/charm quark" sounds odd. Tagged as beauty or charm? L.195: in Table 2 L.196: in Figure 6. Fig.2 and 3: W+bb and tt are indistinguishable in BW. Use colorbrewer2.org to define your colour scheme. L.200: add lumi uncertainty. L.201: collaboration. L.205+ : use align environment.
