[Clascomment] OPT-IN:Absorption of the omega and phi Mesons in Nuclei

[Biplab Dey]

Hi,
Sorry for this late comment. I'm not sure what's the current status is of
the paper, but I'm looking at the April 19 version. Here are my comments:

1) General introduction, 1st para, page 1:
This seems very dense. It's not obvious *why* the things are what you say
they are. Giving references is a fine thing, but I'd say, throw in some
more details. You're stating quite non-trivial facts here. Is there no
simple way (one or two lines) why you expect the properties of vector
mesons to be altered in dense matter, from QCD? Also, I would define
"dense/hot".

Line 24: why? What's so special about low relative momentum? Throw in some
more physics.

2) Line 31: The results *for* the rho meson *have* been *reported* in ...
Follow up with:
In this paper, we present the results for the omega and the phi.

3) Line 33: *were* produced *with* relatively large momenta and a majority
of them decayed outside the nucleus.
(Btw, the term nucleus comes up here for the first time. You need to
explain the experiment details before this.)

4) Line 38: ...increase *in* the meson...

5) Line 42: is the *effect* of colli...

6) Line 52: width is *given by* \Gamma = \Gamma_0 ...

7) Line 59: review of *previous* experiments...

8) Line 61: removed the line beginning "Recent..."

9) Line 62: the *recent* KEK... (if they are recent)
I'd suggest not mentioning omega "meson" every time you mention omega and
phi. It's understood what they are.

10) Line 69: measurement, *the* rho \to ...
Also, fix tense for previous experiments.

11) Line 76: point out the relation between this dilated width with the
lifetime of the omega and nuclear transparancy.

12) Line 81: general comment: don't put the hyphen within the math mode.
$\phi$-$N$ works better, I think.

13) Line 83: check tense.

14) Line 88: suggestion:
In this paper we address these...

15) Line 91: suggestion:
For the JLab experiment, we ...

16) Line 95: suggestion:
A beam of real photons produced via bremsstrahlung from a ?? GeV electron
beam illuminates..., while the leptonic nature of the detected final state
particles *suppresses* FSI effects. (define FSI the first time you mention
final state interactions).

17) Line 99: The CLAS *detector* is ideally suited here because...

18) Line 110: More details about the current experiment can be found...

Okay, this's getting tedious, so I'll stop here. I think the paper needs
quite a bit of polishing, really.
