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 .7 p.application/pdfeng(c) American Physical Society, 2008Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article5776772019-09-06info:eu-repo/semantics/openAccess
