[Eg6_analysis] meeting

[Stepan Stepanyan]

Hello Mohammad,

Nice collection of slides. I assume they will become your talk in few days.
 From way things are presented I am not sure I understand if you will talk
about incoherent analysis or only on coherent DVCS analysis and will show
results on both.
Some specific comments on the slides:
- slide 4, the formula for observable is not visible, at list on my 
computer.
It looks like you inserted a formula as a picture (jpeg, gif, png ...). 
You need
to make it visible, either type it in in power point or in latex and import

- slide 9, can you chose another symbol for \chi^2, it looks X^2.

- slide 16, explaining pi0 subtraction by itself is not simple, but when 
you write
both e4He\pi0/ep\pi0, it gets even more complicated. I suggest to drop 
ep\pi0
part and explain everything for e4He\pi0, then have a sentence below 
that the
same technique is used for ep\pi0
Also, bullets are not so clear, here are some questions:
(a) are the events in the nominator of the ratio R, e4He\pi0(1\gamma), 
are the ones
that will pass the exclusivity cuts?
(b) how you exactly subtract pi0 events, are you subtracting number of 
pi0s from DVCS
sample for each (Q2, x, t, \phi) bin. Are there enough pi0 events (where 
both photons
are detected) to do such subtraction?

- slide 17, will be good to have a slide before this one showing 
(\gamma\gamma)
invariant mass distribution for all combinations (ICIC, ICEC, ECEC) showing
pi0 and applied cuts

- slides 21 and 22, are you going to fit these points with some \phi 
dependent (sin/cos) function?
