Abstract
We report a study of the modes B±→DK± and B±→D*K± where D(*) decays to CP eigenstates. The data sample used contains 275×106BB̄ events at the Υ(4S) resonance collected by the Belle detector at the KEKB energy-asymmetric e+e- collider. The CP asymmetries obtained for DCPK are: A1=0.06±0.14(stat) ±0.05(sys), A2=-0.12±0.14(stat)±0.05(sys) and for DCP*K: A1*=-0.20±0.22(stat)±0.04(sys), A2*=0.13±0.30(stat)±0.08(sys). © 2006 The American Physical Society.
