Dear all,

Laurent has kindly (been) volunteered to read this. Please send comments to him.

Here are my comments:

Dear Mengzhen Wang

Congratulations for this nice observation with three protons in the final state (a record?)

Physics:
L.100: S/sqrt(S+B) is not a significance. Call it a figure of merit if you need a name. How have you determined S? You say "expected". Expected how?

General:

Line-by-line:
Abstract:
Do you examine the phase space? We would say the Dalitz plane.
L.4: The footnote placement is very unfortunate.
L.6: It is unclear why you cut the dibaryon into [cd][ud][ud]. Your analysis should not depend on or assume any internal structure. We suggest you write "Such states could manifest via the decay \Lb->pbarDC (no +), where Dc is a cdudud dibaryon state with mass...
L.18: Here we expect a sentence on the dataset you analyse.
L.42: Remove "Candidate" here to avoid confusion with candidate Lb later. You could write "Selected events"
L.46: you write signal here, but we presume this also applied to your control mode.
L.58: pt is already used in L.33
L.68: use gender-neutral language. We call this a companion in LHCb papers.
L.72: the \Lb vertex.
L.81: remove "again"
L.84: when both following conditions
L.97: from candidates with mass above
L.100: see above under Physics
L.130: candidates -> decays (they are not candidates any longer)
L.131, 176: extract -> determine. Br -> {\br BR}
L.135: total should be in roman
L.138: remove roughly
Eq.1: all subscripts should be in roman
L.159: ... where the uncertainty is statistical only (?).
L.164-5: suddenly "we"
L.211, 233, 284: statistics -> sample size
L.249: we again
Fig.2: The inset does not convey much information. It's just harder to read because of the finer binning. Make this an supplementary plot.
L.269: {\rm BW}
L.272, 278: add resonance after Sigma_c
Figure.3: y axis: this is background subtracted, so not candidates. We suggest "entries" or yield. Caption: You should define what "surrounding" means.
L.311: using data corresponding to 3\invfb
Fig.5: The distance between y labels and legend is too small. Use a BW-friendly palette. This plot is unreadable in BW. You could also use "Box" as we did in paper 2014-020.

[2] Remove capitalisation. You could also just cite the original http://inspirehep.net/record/11881
[18] Use template (svn update first)


Cheers,

Patrick

Dear all,

There is a new paper assigned to us. A rare baryonic decay. Anyone volunteering to collect comments?

Thanks

Patrick
