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)-> D(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.

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)-> D(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.File in questo prodotto:
