Abstract

We present constraints on the angle gamma of the unitarity triangle with a Dalitz analysis of neutral D decays to K-S pi(+)pi(-) from the processes B-0 ->(D)over bar(0)K(*0) ((B)over bar(0)-> D-0(K)over bar (*0)) and B-0 ->(DK*0)-K-0 ((B)over bar(0)->(D)over bar(0)(K)over bar(*0)) with K-*0 -> K+pi(-) ((K)over bar(*0)-> K-pi(+)). Using a sample of 371x10(6) B(B)over bar 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.
