Abstract

We present a measurement of the time-dependent CP-violating asymmetries in neutral B decays to the eigenstate, and an updated measurement of the charge asymmetry in B⁰→K⁺π^-~ decays. In a sample of 33 million Y(4S)→BB̄ decays collected with the BABAR detector at the SLAC PEP-II asymmetric B factory, we find 65_-11 ⁺¹² and 217±18 K⁺π^- candidates and measure the asymmetry parameters S_ππ=0.03_-0.56 ^+0.53±0.111, C_ππ=-0.25_-0.17 ^+0.45±0.14, and A_Kπ = -0.07±0. 08±0.02, where the first error is statistical and the second is systematic.
