<blockquote cite="mid:572CBBA1.6060308@ph.ed.ac.uk" type="cite">Dear
Annalisa,
<br>
<br>
All the reviewers were impressed with the proposal and agreed that
a very thorough job has been made in simulating the analysis and
that the physics case is well made. The comments and suggestions
from the reviewers are collated below
<br>
<br>
Best regards,
<br>
Dan
<br>
<br>
<br>
p7: Are there any (even simple minded) theoretical studies that
indicate that the hybrid baryons should have a comparable width to
the standard N*? Or that the photocoupling is of similar
magnitude?
<br>
<br>
Also could the (disputed) sightings of hybrid states in the meson
sector with widths of similar magnitude to standard mesons be
mentioned as a possible indication that hybrids are not expected
to have large unobservable widths?
<br>
<br>
P7 Fig. 2: Should probably mention what the other curves are
(maybe in the caption) so readers dont have to look up the paper.
<br>
<br>
P9. 3rd para: A result similar -> A theoretical result similar
<br>
<br>
p13: Is there an estaimated timescale for calculations at the
physical pion mass to become available?
<br>
<br>
p22 1st para: providing a nicely complementary range of measurable
photon virtualities -> providing a complementary range of
measurable photon virtualities, including the gap region for the
lower beam energy setting.
<br>
<br>
p24 called FASTMC -> (FASTMC) this had already been
defined
<br>
<br>
p27 1st para: with a detection efficiency lower than in the
inclusive case where the value of W_rec is determined-> with a
correspondingly lower
<br>
<br>
<br>
p32 1st para: since kinematic region -> since the kinematic
region
<br>
<br>
p38 1st para: completely dominates ( this assumes the forward
tagger is triggered on charged particles i.e. ignoring the photon
flux - text is probably OK as is though)
<br>
<br>
p38 3rd para: the farm -> a CPU farm
<br>
<br>
p43: These ratio -> These ratios
<br>
<br>
-------------
<br>
<br>
FASTMC is an important part of you studies. Could you provide some
more details on it?
<br>
<br>
Figs 6: what are the solid lines?
<br>
<br>
P.21, Fig 12. In the text it says that positive torus current
causes increase in minimum detectable $Q^{2}$, while negative
current lowers the minimum values. Fig. 12 shows that in both
cases minimal $Q^{2}$ is about $0.2 GeV^{2}$. Could you clarify?
<br>
<br>
P. 48, Eq 8, last line: $105 cos\theta \to 105 cos^{2}\theta$
<br>
<br>
Fig 15, right. What are the dots?
<br>
<br>
Fig 20. How do you select exclusivity cuts?
<br>
<br>
Fig. 25, 26: The depletion at 35 degrees is much more prominent
for p and $K^{+}$ than for $\pi^{-}$. Could you clarify why?
<br>
<br>
-------------
<br>
<br>
Since the full proposal is presenting such detailed studies of
proposed analysis and running conditions, it will be nice to see
somewhere a short "executive summary"
<br>
where with tables or simple statements there will be details of
the overall proposal : i.e. most important expected physics
outputs and effects in hadron structure models, specific running
conditions (i.e a table including triggers and effects on other
parallel programs in CLAS12), expected more difficult points on
the analysis -model dependences, backgrounds, ambiguities,
acceptances ...... and so on.

<br>

I hope to have finished reviewing the proposal later today/early

How is everyone else doing?

I'd like to thank you for agreeing to be part of the Hybrid

<br>
In attachment you will find the charge with deadlines and
duty.
<br>
Annalisa D'Angelo is acting as contact person. I'm expecting
he will
<br>
provide all necessary support (supporting material, missing
info,
<br>
answers, ...) in a timely manner in order to respect the
deadline.
<br>
Thanks again for your contribution.
