Introduction

• Investigation on variety of B physics at Super-KEKB

  • BK/, /K*  high momentum K/ separation (~ 4 GeV/c)
  • BKll  low momentum / separation ( <1 GeV/c)
  • high purity on full B reconstruction
  • Requires improvement of current Belle PID system
  • CDC + TOF + ACC : K ID eff. 88%,  fake rate 8.5%
