|q/p| Measurement from B0->D*l nu Partial Reconstruction
Abstract
We present a new measurement of CP violation induced by B0 B0bar oscillations, based on the full data set collected by the BaBar experiment at the PEPII collider. We use a sample of about 6 million B0->D* l nu decays selected with partial reconstruction of the D* meson. The charged lepton identifies the flavor of the first B meson at its decay time, the flavor of the other B is determined by kaon tagging. We determine the parameter dCP = 1 - |q/p| = (0.29+-0.84+1.78/-1.61) 10-3.
