Aubert, B. et al. (2008) Measurement of the CP Asymmetry in b→sγ Using a Sum of Exclusive Final States. Physical Review Letters, 101 (17). p. 171804. ISSN 0031-9007Metadata only available from this repository.
We perform a measurement of the CP asymmetry in b→sγ decays using a sample of 383×106 BB̅ 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 Xs containing an s quark. We measure the CP asymmetry to be -0.011±0.030(stat)±0.014(syst) for a hadronic system mass between 0.6 and 2.8 GeV/c2.
