<p>Dear Victor,</p>
<p>yes I have considered the numbers suggested by Volker in the
attached message and I have considered the energy leakage:</p>
<p>E'min> 2.0 GeV -> 1.8 GeV (180-200 MeV energy leakage)</p>
<p>E'Max < 7 GeV -> 6.6 GeV (400MeV energy leakage) at E = 7.5
GeV</p>
<p>E'Max < 6 GeV -> 5.6 GeV (400MeV energy leakage) at E = 6.5
GeV</p>
<p>In fact the original numbers that were proposed were based on
very similar physics considerations.</p>
<p><br>
</p>
<p>All the best Annalisa<br>

Subject: Re: Range of the scattered electron energies
I think Victor calculated a sharp threshold without considering the
resonances have broad widths for hybrids.
I suggest the following, i.e. W thresholds are above 3 GeV in either case.
7.5 GeV: E'min>2.0 GeV
6.5 GeV: E'min>2.0 GeV
For the upper E' I suggest to lower the numbers so that resonance width
are taken into account.
7.5GeV: E'max< 7.0 GeV
6.5GeV: E'max < 6.0 GeV
Thresholds may have to be adjusted for energy leakage.

<pre wrap=""> Hi Annalisa,
Your numbers look as unchanged in comparison we discussed last Friday. Do they account the window from minimal to maximal energy of scattered electro we discussed?
Best Regards,
Victor

Dear All,
after our last Friday meeting and following message exchange, I have
summarized the results in the attached slides.
Please send me your corrections if any this morning. I will otherwise
send the sides to Valery, as requested.
All the best
Annalisa
p.s. I have used the calibration curves for FT to calculate the energy
loss n the FT calorimeter:
1800 MeV -> 2 GeV (180 MeV - 200 MeV energy leakage loss)
5600 MeV -> 6 GeV (400 MeV leakage loss)
6600 MeV -> 7 GeV (400 MeV leakage loss)
