Thank you very much for clarifications!

Best Regards,

Dear Victor,

yes I have considered the numbers suggested by Volker in the attached 
message and I have considered the energy leakage:

E'min> 2.0 GeV -> 1.8 GeV (180-200 MeV energy leakage)

E'Max < 7 GeV -> 6.6 GeV (400MeV energy leakage) at E = 7.5 GeV

E'Max < 6 GeV -> 5.6 GeV (400MeV energy leakage) at E = 6.5 GeV

In fact the original numbers that were proposed were based on very 
similar physics considerations.


All the best Annalisa

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.
