Abstract

We present constraints on the angle γ of the unitarity triangle with a Dalitz analysis of neutral D decays to KSπ+π- from the processes B0→D̅ 0K*0 (B̅ 0→D0K̅ *0) and B0→D0K*0 (B̅ 0→D̅ 0K̅ *0) with K*0→K+π- (K̅ *0→K-π+). Using a sample of 371×106 BB̅ pairs collected with the BABAR detector at PEP-II, we constrain the angle γ as a function of rS, the magnitude of the average ratio between b→u and b→c amplitudes.
