Hello,
What is the pin for the vidyo link. None of the ones that I know work.

Dear all,
Here are my (and Pieters) comments on PAPER-2014-039 ("First observation of a baryonic $B_c^+$ decay"). Textual suggestions are in attachment. I will submit to CDS on Tuesday.
These are the most important comments:
1) We would like a stronger first paragraph, where the motivation is optimally presented for the PRL reader. (a) We suggest to move L.12 - L.17 to the 2nd sentence; "The baryonic decays of B mesons are important, ... in the low mass region." (b) We suggest to move the 'prediction' of L.190 to the first paragraph. (c) Q: does a similar measurement also exist in Bs or Bu decays?
2) L.127 Here you correct the measured mass by +0.20 MeV due to FSR. (a) Q: How is this usually done within LHCb? Did we always have such a correction to the mass measurement? (b) Q: The uncertainty to this correction is 0.03 MeV. Does that purely come from MC statistics, or does the uncertainty include theoretical uncertainties as well?
3) L.143 You discuss a new selection for the BR(Bc) measurement compared to the M(Bc) measurement. Q: To reduce the systematics, you decrease the yield from 23.9 to 19.3 events. Since the statistical unc is dominant, is this reduction in statistics indeed compensated by a smaller systematic unc?
4) L.151-154 and Tab.2. We could not follow how you determined the single-track efficiency. (a) Q: How did you use Lc->pKpi or D*->D0pi events? (b) Q: Does the single-track efficiency only refer to tracking efficiency on reconstructable effects? (c) Q: Wat do you mean with "Reco. of p,pbar" in Tab.2 ? Is that the same single-track efficiency? (d) Q: How is the unc due to the acceptance of 0.7% determined, in Tab.2 ?
5) L.135 The systematic uncertainty of the combined result is larger than the systematic unc of your measured value, that is one of the inputs. In App. A you explain a bit more: in the combination you weight the inputs using their total uncorrelated unc. Then, presumably, you add the correlated sys uncertainty to the final result. But how do you determine the total systematic uncertainty on the final result?
Cheers, Niels

I also uploaded the comments to the Bc paper. (We thought it was easier that Patrick submitted separately.)
