Abstract: | We present constraints on the angle γ of the unitarity triangle with a Dalitz analysis of neutral D decays to K S π + π − from the processes B 0 → ¯¯¯ D 0 K * 0 ( ¯¯¯ B 0 → D 0 ¯¯¯¯ K * 0 ) and B 0 → D 0 K * 0 ( ¯¯¯ B 0 → ¯¯¯ D 0 ¯¯¯¯ K * 0 ) with K * 0 → K + π − ( ¯¯¯¯ K * 0 → K − π + ). Using a sample of 371 × 10 6 B ¯¯¯ B pairs collected with the BABAR detector at PEP-II, we constrain the angle γ as a function of r S , the magnitude of the average ratio between b → u and b → c amplitudes. |
