Paper: Search for Lepton Flavor Violation in the emu Continuum

Line: 18 to 18

2.58: You say "missing transverse momentum" and denote it "ETmiss". Then it should be "missing transverse energy".

No, it's a vector quantity and in ATLAS we properly call it missing transverse momentum, if they call it missing transverse energy they'll be asked to change it back. (James F)

2.65: How does the single top process produce two prompt leptons, one being an electron and one being a muon and both leptons having opposite electric charge?

3.50: "two hypothesis" -> "two hypotheses"

Line: 36 to 38

Ref 24: Same as above, but I could not guess what the year is from "001", also because the page is atypically only with two digits. Needs double check.

James F's comments

General Comments:

A) The paper neglects to mention of searches at HERA which are sensitive to the same physics:

stop production via R-parity violating SUSY:

This is a 90 degree rotation of the diagram for 1. The HERA experiemnts set limits on %$ \lamba_{131}$%. See

H1 Collab., F.D. Aaron et al., Eur.Phys.J.C71 (2011) 1572

ZEUS Collaboration; S. Chekanov et al. Eur. Phys. J. C 50 (2007) 269

it would be nice to at least reference them.

B) Couldn't this process also occur via t-channel exchange of a LFV leptoquark?

like those in:

H1 Collab., F.D. Aaron et al., Phys. Lett. B701 (2011) 20 ,

would the present search also be able to improve on those exclusions?

Specific comments:

page 1 line 42-43: "The diagram ...has the same cross section" probably better as "The process ... has the same cross section"

page 1 line 69: More needs to be said about the 0.72 and 0.28, e.g. which PDF set is used to get this weighted sum, what is the associated uncertainty? How stable vs choice of alternative PDF? We need to know this to judge whether the limit vs coupling plot makes any sense.

references:

I agree with Adrian on the JHEP references, I don't know however if the paper is following some established ATLAS convention
