| Abstract: | We perform a measurement of the C P asymmetry in b → s γ decays using a sample of 383 × 10 6 B ¯¯¯ B events collected by the BABAR detector at the SLAC PEP-II asymmetric B factory. We reconstruct 16 flavor-specific B decay modes containing a high-energy photon and a hadronic system X s containing an s quark. We measure the C P asymmetry to be − 0.011 ± 0.030 ( stat ) ± 0.014 ( syst ) for a hadronic system mass between 0.6 and 2.8 GeV / c 2 . |
