1 Study of MDC tuning

2 Tracking eff v.s. Transverse Momentum (proton)

3 Tracking eff v.s. Transverse Momentum (antiproton)

4 Tracking eff v.s. Transverse Momentum (positive pion)

5 Tracking eff v.s. Transverse Momentum (negative pion)

6 Tracking eff v.s. cos[theta] (proton)
WRONG!!!

7 Tracking eff v.s. cos[theta] (antiproton)
WRONG!!!

8 Tracking eff v.s. cos[theta] (positive pion)

9 Tracking eff v.s. cos[theta] (negative pion)

10 Muon momentum resolution
Previous /GeV New / GeV σ data × 10 −2 ± × 10 −6 σ MC × 10 −2 ± × 10 −6 × 10 −2 ± × 10 −6 σ MC/σ data – 1 (%) − ± ±
