摘要： We report a measurement of the CP-violation parameter φ1 obtained in a time-dependent analysis of B0→D¯(*)0h0 decays followed by D¯0→KS0π+π− decay. A model-independent measurement is performed using the binned Dalitz plot technique. The measured value is φ1=11.7°±7.8°(stat)±2.1°(syst). Treating sin2φ1 and cos2φ1 as independent parameters, we obtain sin2φ1=0.43±0.27(stat)±0.08(syst) and cos2φ1=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 ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. 出版者： College Park: American Physical Society 出版日期： 2016-09-06 出處： Physical Review D, 2016-09, Vol.94 (5) 版權： Copyright American Physical Society Sep 1, 2016 識別號： ISSN: 2470-0010 識別號： EISSN: 2470-0029 識別號： DOI: 10.1103/PhysRevD.94.052004
