Measurement of time-dependent CP-violating asymmetries in B-0 -> K-*0 gamma(K-*0 -> K-S(0)pi(0)) decays

Abstract:

A measurement of the time-dependent CP-violating (CPV) asymmetries in a b → sy process through the exclusive decay, was performed. A systematic uncertainty of 0.02 (0.02) due to tagging asymmetries in the signal and 0.02 (0.02) due to imperfect knowledge of the probability distribution function (PDF) was included. An event-shape Fisher discriminant in the maximum-likelihood fit was employed, from which the CPV measurements were extracted. For the continuum background, the functional form of t...
