CP Violation in b → s Decays and New Physics Phases

2005 International Journal of Modern Physics A  
We present new measurements of CP-violation parameters in B0->phi/Ks, K+K-Ks, f0(980)Ks, eta'Ks, omega/Ks, Pi0/Ks, and K*0(KsPi0)/gamma decays based on a sample of 275x10^6 BBbar pairs collected at the Y(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. One neutral B meson is fully reconstructed in one of the specified decay channels, and the flavor of the accompanying B meson is identified from its decay products. CP-violation parameters for each of the decay
more » ... each of the decay modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays. All results are preliminary.
