Measurement of γ in B^±->D^(*)0 K^± decays by a Dalitz analysis of D^0 ->KS&-circ;&+circ;
Abstract
We present the measurement of the unitary triangle angle γ obtained studying the direct CP violation in the decay B^±->D^(*)0 K^± (with D^* ->D^0 ^0,D^0 γ) and D^0 ->KS^-^+. The method is based on the analysis of Dalitz distribution of the three-body decay of the neutral D meson and exploits the interference between D^0 and D^0 to extract both the weak and strong phases. The analysis is performed using a sample of 227 million B B pairs recorded at the υ(4S) resonance with the BaBar detector at the PEP-II asymmetric e^+e^- storage rings.
