PID capability on test beam data

From
typical values (single photon
|
|
|
resolution
13mrad and 6 detected
|
|
|
photons)
we can estimate the
|
|
|
Cherenkov
resolution per track:
|
|
|
5.3mrad;
|
|
|
->
4.3sigma p/K separation a 4GeV/c.

pions at 4GeV/c and
'kaons' (pions at 1.1GeV/c with the same

Cherenkov angle
as kaons at 4GeV/c). Details: NIM paper
