Conclusion

• TOF wall at 15 m gives better resolution but more
  misidentification at low momentum
• Improvement of RPC time resolution saves
  efficiency at low momentum
• Worse momentum resolution is not so crucial as
  time uncertainty
• Obtained efficiency of K- identification will be
  applied to D0 detection simulation
