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.
Illustration of PID performance: Cherenkov angle distribution
for pions
at 4GeV/c and 'kaons' (pions at 1.1GeV/c with the same Cherenkov angle as kaons
at 4GeV/c). Details: NIM paper
