  1. Prospects for precision of f3(GLW+ADS) ・Signal extraction for BDK, DKp (@ 10/ab) New PID Current PID Efficiencies Signal : + 10% Xp BG : − 20% qq BG : − 50% Xp BG Similar effect on BDK, DCP+ (KK,pp) ・Precision of f3 Modes : DK and D*K (DKp, DCP+, DCP-) Assumption : Current result f3=70°, dD=23°, rB(DK)=0.1, rB(D*K)=0.1, dB(DK)=110°, dB(D*K)=-40° Bayesian method by Y. Horii (yhorii@awa.tohoku.ac.jp) 3°  2° (New PID) @ 50/ab

  2. Method of f3 fit Contact : Y. Horii (yhorii@awa.tohoku.ac.jp) , , …… 0. Extract signals. 1. Calculate observabls. 2. Obtain probability. (O1=RADS, O2=RCP+, O3=RCP-, O4=ACP+, O5=ACP-, O6=dD)
