A study on the measurement of φ≡ using a sample of 144×106 ≡- →λπ- decays having an average polarization of 3.7% was presented. The polarized ≡-'s were produced by directing an 800 geV÷c proton beam onto a 2 mm ×2 mm× 60 mm cu target at angles of +3 and -3 ...
We present an improved measurement of CP-violating asymmetries in B 0→π+π- decays based on a 78 fb -1 data sample collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+ e- collider. We reconstruct one neutral B meson as a ...
The CP violation parameters in Bo → π +π- decay were investigated. The flavor of the accompanying B meson was identified by reconstructing B o→π+π- CP eigenstate. It was observed that the expected sensitivity was optimized using the ratio LR. The study sho ...
The measurements of time-dependent decay rates for B 0(B̄0) → D(*)∓π ∓ decays and extraction of CP violation parameters containing φ3 were discussed. It was found that a 140 fb-1 data sample, which contained 152 × 106 BB̄ events, was used in the measuremen ...
