We report on a measurement of the Cabibbo-Kobayashi-Maskawa CP-violating phase γ through a Dalitz analysis of neutral D decays to KS0π−π+ in the processes B∓→D(*)K∓, D*→Dπ0, Dγ. Using a sample of 227×106 BB¯ pairs collected by the BABAR detector, we measure the amplitude ratios rB=0.12±0.08±0.03±0.04 and rB*=0.17±0.10±0.03±0.03, the relative strong …
