Particle Identification

Particle ID.

• Barrel Region (-1.70<η<1.70)
  • DIRC: e/π/K/p
    • π/K ≥ 3σ up to 6 GeV, ≥ 4σ up to 8 GeV
    • K/p ≥ 3σ up to 12 GeV
    • e/π 10:1 for 0.7 < p < 1.2 GeV/c
  • EMCal
    • γ/π^{0<\sup> discrimination up to 14 GeV (can be improved with preshower layer)}
  • Instrumented Flux Return
    • Muon vs neutral hadron discrimination
    • Neutral hadron (n,K_S) angular resolution ~20 mrad
