Abstract

We report a measurement of the CP-violation parameter ?1 obtained in a time-dependent analysis of B0?D(?)0h0 decays followed by D0?KS0?+?- decay. A model-independent measurement is performed using the binned Dalitz plot technique. The measured value is ?1=11.7��7.8�(stat)�2.1�(syst). Treating sin2?1 and cos2?1 as independent parameters, we obtain sin2?1=0.43�0.27(stat)�0.08(syst) and cos2?1=1.06�0.33(stat)-0.15+0.21(syst). The results are obtained with a full data sample of 772�106BB pairs collected near the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. � 2016 American Physical Society.
