Study of Time-Dependent CP-Violating Asymmetries in b->sq q Decays

Abstract

We present a measurement of CP-violation parameters in the b->sq q penguin transitions (q=s,u,d) based on a 78/fb data sample collected at the Y(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. One neutral B meson is reconstructed in the phiks, K+K-ks, or eta'ks decay channel, and the flavor of the accompanying B meson is identified from its decay products. CP violation parameters for each of the three modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays.
