 +-------

 +L3: not sure it's correct: a very week coupling to the Higgs, i.e., if they neutrinos get their mass as the other fermions in the SM, should be considered ​ "SM ", even if esthetically we don't like it.

 +L76: thereby defined ==> thereby defining a

 +L95: where does the Ht< 100 GeV cut comes from?

 +Type B
 +
 +While it is clear how the limits on sigmaxBR are derived, It is not clear from the
 +discussion how the limits on M_\Sigma are gotten.
 +
 +
 +
 +Type A
 +
 +
 +L3 :
 +"​unambigous evidence of phenomena not foreseen"​ … are we really sure the phrasing is
 +correct ? Is the fact that neutrinos have mass a "​phenomenon"​ ? Isn't the massless
 +neutrino an assumption in SM ?
 +
 +
 +L16: 
 +please review the English. " … couplings does not" -> "​couplings do not" . But also,
 +which cross-section is not affected ? 
 +

 +
 +L56
 +Suggested re-phrasing : " .. while parton shower and hadronization are implemented
 +using PYTHIA"​.
 +But which partons and hadrons are we speaking about ? Underliying event ? The
 +diagram in Fig 1 has no parton in the final state , so this is confusing.

 +"that match a reconstructed (remove "​to"​)"​ , also remove "​extrapolated from the

 +
 +L84-85
 +"no rejection as candiate …" ​ really did not understand what it means, avoid double
 +negatives. "Three independent algorithms" ​ ?
 +
 +L91
 +p^\mu -> p^e
 +
 +L107
 +"​conversions of virtual photons" ​ … does a "​virtual photon"​ actually "​convert"​ ? The
 +conversion process usually refers to a real photon interacting with material. A
 +virtual photon always transforms into something.

 +General comments:
 +none
 +
 +
 +Specific comments:
 +Abstract: maybe the first 3 sentences can be merged somehow...
 +
 +L 2-4:
 +
 +L 23: Because -> Since
 +
 +L 25: Also, -> Also
 +
 +L 25-26: Why these kind of decays are not considered in the analysis? Maybe it's worth explaining
 +
 +L 28-29: I would dropp "for the heavy and light leptons"​
 +
 +L 32: From "The production",​ I would change into "The strength of the coupling between Sigma and the lepton alpha is proportional to:"
 +
 +L 44-45: I would drop at least "​measured"​ since the muon tracks are mostly "​measured"​ in the tracker...
 +
 +L 61-62: I would change into: "A smaller contribution to the background comes from the diboson ZZ channel..."​
 +
 +L 64: three EW-bosons -> three EW-boson production
 +
 +L 68: here you introduce the "​internal"​ and "​external"​ convertions,​ but you don't explain what they mean, you do it in par. 4-5. I suggest to re-organize the thing and make sure that immediately after any "​non-trivial"​ term the corresponding ​ definition is present (the same stand for asymmetric conversion in L 106).
 +
 +L 77: I would drop all the (i) (ii) etc. since they are not used as references
 +
 +L 84: I don't understand the (iii): if the rejection is not applied simply don't mention it
 +
 +L 85: About (iv), if it's the electric charge is checked to be consistent from the 3 algorithms I would not stress the curvature more than the charge (as you do) otherwise it's ok like this
 +
 +L 87: I would drop PF everywhere
 +
 +L 99-100: "one or two entries..."​ -> one or two opposite-sign/​same-flavour dilepton pairs
 +
 +Figure 2: expand the y-axis range of left figure since there is one error bar which is not completely included in the plot. I would use different colors instead of different fill styles, much clearer
 +
 +L 114: here you describe once again the sources of background, maybe you can prune the background-related sentences in the other paragraphs.
 +
 +L 132: since, as far as I understand, there is no 4-lepton veto the last part of the sentence sounds incorrect, because it's not necessary that the "​soft"​ lepton from the conversion is undetected in order to make this final state a background.
 +
 +L 209: "​defined Eq." -> "​defined in Eq."
 +
 +L 246-248: I would drop the last sentence  ​
