[Hps] Second round of collaboration review of our first physics paper

[osipenko]

Thank you Stepan for sending the PDF!

I approve the draft, and I have few suggestions:

1) page.1 after Eq.1 - use "dimensionless" parameter;

2) end of page 1 - at least to me the statement about "quantum effects" 
is not clear, are these simple loops of heavy particles? Then perhaps 
you may mention here the masses of these particles that you expect 
indicating the range of epsilon;

3) page 2 second paragraph - you mention mass range up to 500 MeV, but 
never justify why you covered only <81 MeV, although one may guess that 
it is matter of statistics, but I would suggest put it explicitly into 
the text somewhere...;

4) beginning of Section IV - I would suggest "We expect a heavy photon 
to appear as a Gaussian-shaped resonance...";

5) page 4 previous to last line - perhaps 0.5 MeV not .05, right?

6) Eq.3 - alpha is undefined,

7) page 5 previous to last sentence before section VI - "systematic" is 
a jargon, twice serial "due to", rephrase like "When scaling...the 
primary systematic uncertainty is..."

8) same place - in Fig.3 the limits using "all statistical and 
systematic uncertainties" are shown, actually (if contribution of 
systematic errors is significant) you may provide a better insight on 
the results by providing also statistical contribution only (e.g. adding 
on the plot another area under the cyan), in this way a reader can 
figure out if you will gain something running more beam time or the 
result is already dominated by systematics and no further improvement is 
possible regardless new runs. It may give a basis to state that "running 
for more beam-time we will get much more precise limits" (or not)...

Best Regards,

                            Mikhail.
