Abstract:
The particle identification of charged hadrons, especially
for the separation of K and π , is crucial for the flavour
physics study. Ionization measurement with the cluster counting technique, which has a much less fluctuation than traditional dE / dx measurement, is expected to provide better particle
identification for the BESIII experiment. Simulation studies, including a Garfield++ based waveform analysis and a performance
study of K / π identification in the BESIII offline software
system have been performed. The results show that K / π separation
power and PID efficiency would be improved appreciably in the momentum range above 1.2 GeV/c using cluster counting technique
even with a conservative resolution assumption.
