Very nice presentation overall! My main comment is that you mention 'SPS' and 'DPS' multiple times through the talk, but it only gets introduced at slide 11. You indeed said that it will be introduced later during the talk, but in this case it really seems like it would be easier to understand the talk if these terms were introduced at the very beginning. If you analysis can distinguish between SPS and DPS production than this also serves as a good motivation for the analysis. Furthermore, in page 2 you introduced CS and CO production, but it is not mention again later on. Could this be skipped?

p2: Try avoid using abbreviations, especially the ones like CS and CO that most people will not be familiar with.

Could you explain a bit more the difference between color singlet and color octet and how that translates into the shown feynman diagrams. Perhaps also mark the relevant differences in the diagrams more clearly.

Chuck: All good points. I removed the confusing language from the introduction. This measurement is not actually targeting any specific models, so I just dropped the references to the specific "color-singlet" and "color-octet" production modes. Just referencing "QCD quarkonia production models"

p10: Do you also require the two muon tracks to be compatible with the primary vertex? I would expect this to be a strong way of reducing the background from pileup.

Chuck: This is true, but we explicitly want to keep some of the pileup in order to estimate the pileup overlapping the signal delta-z=0. (By comparison, we could remove lots of non-prompt J/psi's by cutting on flight distance, but we use the high-tau shape to fix the non-prompt contribution at tau=0.)
