Hello Mohammad,<br>
<br>
Nice collection of slides. I assume they will become your talk in
few days.<br>
From way things are presented I am not sure I understand if you will
talk <br>
about incoherent analysis or only on coherent DVCS analysis and will
show <br>
results on both. <br>
Some specific comments on the slides:<br>
- slide 4, the formula for observable is not visible, at list on my
computer.<br>
It looks like you inserted a formula as a picture (jpeg, gif, png
...). You need<br>
to make it visible, either type it in in power point or in latex and
import<br>
<br>
- slide 9, can you chose another symbol for \chi^2, it looks X^2.<br>
<br>
- slide 16, explaining pi0 subtraction by itself is not simple, but
when you write <br>
both e4He\pi0/ep\pi0, it gets even more complicated. I suggest to
drop ep\pi0<br>
part and explain everything for e4He\pi0, then have a sentence below
that the<br>
same technique is used for ep\pi0 <br>
Also, bullets are not so clear, here are some questions:<br>
(a) are the events in the nominator of the ratio R,
e4He\pi0(1\gamma), are the ones <br>
that will pass the exclusivity cuts? <br>
(b) how you exactly subtract pi0 events, are you subtracting number
of pi0s from DVCS<br>
sample for each (Q2, x, t, \phi) bin. Are there enough pi0 events
(where both photons<br>
are detected) to do such subtraction?<br>
<br>
- slide 17, will be good to have a slide before this one showing
(\gamma\gamma)<br>
invariant mass distribution for all combinations (ICIC, ICEC, ECEC)
showing <br>
pi0 and applied cuts<br>
<br>
- slides 21 and 22, are you going to fit these points with some \phi
dependent (sin/cos) function?<br>

<br>
Here i attached a pdf file in which i collected all up to date
results of my analysis.
<br>
The coherent channel shows a good agreement with the simulation.
On the side of the incoherent channel, we still have the issue of
the shifts in the missing mass squared of ep and egamma, see slide
number 28 for the comparison between the simulated and the
experimental incoherent DVCS. Please let me know if you have any
suggestions or comments.
<br>
<br>
Best regards,
<br>
M. Hattawy.
