Re: [Bfys-physics] Fwd: First circulation of publication draft for PAPER-2017-039, Search for the suppressed $\Lambda^+_c \to p \mu^+ \mu^-$ decay and observation of the $\Lambda^+_c \to p \omega$ decay
Dear Patrick, Tim Gershon also insisted on some systematic uncertainty, and I think it was requested by the RC at some point. So this is a widely shared concern. They both proposed to include a systematic using the RMS of the efficiency over q2, but I think to include the efficiency in q2 bins would be even better.

Dear Mick, Here are my comments on the paper. We need to decide how much we insist about my 1st physics comment. Anyone else agrees? //===================================================================
Physics:
- L.147: We disagree with this strategy. As you do not provide an efficiency map versus the Dalitz plane, interested readers cannot recast your limit to their favourite model. You actually do not even give an indication of how the efficiency varies on the DP. We suggest you either assign a systematic uncertainty or provide an efficiency map.
- L.153: We hope that what you did is not what is described in the text. The polynomial pdf describes the background, not the non-resonant region. You must have tried to fit the \Lc somehow in order to get a limit. Why don't you show the peak (which my be negative) and give the fitted yield?
General:
- PRL does not have sections.
- You mix British and American spelling. You may use either (PRL will translate if needed) but be consistent.\
- It is a pity no additional plots are provided.
Line-by-line:
Abstract: "A search for contributions from flavour-changing neutral currents to the decay \decay{\Lc}{...}". Below, we suggest to add the range of q^2 your BF limit corresponds to.
L.18-20: you mix mumu and ll modes. At this level you should stick to ll. Aslo, use \ellell and define what \ell stands for.
L.20: .\footnote{...} The (you miss the space and have the dot at the wrong place)
L.23: vector-meson
L.24: In this Letter. But actually the letter reports only. So here you mean the analysis.
L.27: [4] reporting a signal yield of 11.1\pm5.0\pm2.5 and an upper limit...
L.29: remove "It is worth pointing out that" (everything we write is worth pointing out)
L.31: Remove However
L.32: stimulates -> motivates
L.33: Similar processes in the \Dp system have not been found to date.
L.36: using data corresponding to 3\invfb
L.37: to the decay \decay{\Lc}{p\phi} with \decay{\phi}{\mumu}
L.37: add that \phi stands for \phi(1020) throughout.
L.67: at the $pp$ collision point or in \bquark-hadron decays. (do you need the word "prompt"?)
L.75: events -> decays
L.78: required to be of good quality and have \pt
L.82: Three dimuon mass regions are defined : * a region... and so on
L.83 and everywhere else: \mevcc already contains a space before MeV, so do not add one yourself.
Fig.1: we suggest to add "\phi region"
L.103: remove "candidates"
L.103: for the final optimisation of the selection
L.106: no need of "baryon"
L.112: the one -> that
L.113: An irreducible background originates from (it's not dangerous once identified)
L.115: \rhoz. the \omega meson
L.123: remove "the following formula"
Table 1: all rows are called "efficiency ratio". You could drop that term.
L.128: remove "the following formula:" (never put a colon)
L.140: remove "one"
L.146: remove "the relevant columns of"
L.147: according to a phase-space model.
L.148: see above. But the actual decay is not a model. It's Nature.
Fig.2: We suggest you add the \Lc component to the top plot. Plese label the plots as non-resonant, phi and omega so they can be re-used in talks easily. The - on mu- should be longer (also in following plots).
L.153: For the nonresonant region, a first-order... (but see above)
L.157-9: no need to refere to figs 2a, 2b, 2c. One fr Fig 2 is enough.
L.158: candidates -> decays
L.158: events -> candidates
Fig.4: It's hard to put a {\cal B} on an axis legend, but avoid BR while you write B in the paper.
L.165: the -> an
L.168, 172, 174, 176: remove ":"
L.176+1: . -> ,
L.182: 5.0\sigma (no space)
L.184: from BaBar -> by the BaBar collaboration
[1] There should be no number 7 in the reference
[5] why not R_K*?

[28] use the template

Dear all,
This paper was assigned to us on the 19th. If I remember correctly it is the analysis of the new PhD student at ATLAS, Marko.
Marko did his Master thesis on this channel, but the results presented here are those of the Krakow analysis. They are slightly more precise. I don't know the history.
Mick, please let the list know by when you need the comments.
Cheers,

The deadline is on the 2nd of November, so next week on Thursday.
