Hello Luca,<br>
<br>
Thanks for the work and the note. Sorry, meeting was cut short so I
could not<br>
ask my questions. So, here they are (I read not and will comment on
it) - <br>
- I am confused with your definition of \delat E and ECal
resolution. In the proposal <br>
we quoted sigma/E=4.5%/sqrt(E) for ECal resolution. This means that
the sigma will <br>
be sigma=4.5%*sqrt(E). This will end up for 1.5 GeV energy sigma ~
4.9 MeV, for <br>
2.2 GeV sigma~5.9, and for 6.6 GeV it is ~10 MeV. So, I am not sure
where this 30 MeV,<br>
20 MeV, and 6 MeV come from, and what they represent.<br>
<br>
- From your slides, Eq.(8) in the note is for 2.2 GeV and Eq.(9) is
for 6.6 GeV. Please <br>
mention that i the note<br>
<br>
- on page 3, you have L=34, which I assume is the with for 23
modules and it includes<br>
thickness of wrapping, while H=6.5 cm, that is calculated without
taking into account <br>
vertical space between modules. It may not matter, but will be
better to be consistent.<br>
I do not understand what is h=4 cm, if it is distance from the x-z
plane to the bottom<br>
of the face of the ecal crystals it should be 2 cm, since the gap
between two ecal modules<br>
is 4 cm.<br>
<br>
- Table 2 and Fig. 3, this fiducial acceptances, they do not take
into account magnetic field,<br>
is not it.<br>
<br>
I am attaching the note that we wrote with Takashi, will be
interesting to compare your numbers <br>
with numbers in the note, it seems your cross sections are much
higher.<br>
<br>
Regards, Stepan<br>

I think we passed the maximum length of meeting due to the time
change.
<br>
So we will have to continue the discussion next week.
<br>
<br>
Luca, could you send your slides around so everybody sees your
results
<br>
and conclusion?
<br>
<br>
Sorry for the problem, next week Europe will be back on the
usual
<br>
schedule and this issue should not bother us again.
<br>
<br>
Best,
<br>

Ok, no problem.
<br>
I wrote a report on what I did, you'll find it in the attachment
along with the slides.
<br>
If you have any question, please write me.
