Constraints on the CKM angle gamma in B^0-->[overline D]0K^(*0) and B^0-->D^0K^(*0) from a Dalitz analysis of D^0 and [overline D]^0 decays to K_Sπ^+π^-
2009
We present constraints on the angle gamma of the unitarity triangle with a Dalitz analysis of neutral D decays to K_Sπ^+π^- from the processes B^0-->[overline D]^0K^(*0) ([overline B]^0-->D^0[overline K]^(*0)) and B^0-->D^0K^(*0) ([overline B]^0-->[overline D]^0[overline K]^(*0)) with K^(*0)-->K^+π^- ([overline K]^(*0)-->K-π^+). Using a sample of 371×10^6 B[overline B] pairs collected with the BABAR detector at PEP-II, we constrain the angle gamma as a function of r_S, the magnitude of the average ratio between b-->u and b-->c amplitudes.
