The paper is generally pretty good and presents an interesting search for RPV SUSY.

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

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

C) What about signal processes like %$d \bar{d} \rightarrow \tau \bar{\mu}$% with leptonic tau decay, were they considered?

D) What about processes such as u %$\bar{b}\rightarrow e \mu$% are they perhaps constrained by B-physics measurements, if not why ignore them? (apart from the relatively small PDFs)

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 65-66: sloppy phrasing here, the strange PDFs don't suppress the %$ss \rightarrow e\mu$% process, without them it wouldn't happen at all, please reword.

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.
