      • Excellent Trigger
        - Extremely Fast Track Finder (L1)
        - Silicon Impact Parameter (L2)
      • Particle ID
        - dE/dx ; π/K ∼ 1.3σ
        - ToF ; S/N x 20 with ε=85% (p<2GeV);
      • Flavour Tagging (εD2∼4% → 5% expected)
      • Vertex Resolution
        - primary=10μm
        - secondary=14μm
      • Mass Resolution (15MeV for J/ψ)
      • Proper Decay Time Resolution (σt=67fs → 50fs with L00)
      • Kinematics of the event
        (Correlation between mass, charge, momentum unbalance)
