摘要

Article history: Received 16 April 2012 Received in revised form 12 May 2012 Accepted 6 June 2012 Available online 9 June 2012 Editor: W.-D. Schlatter Using 1.0 fb−1 of pp collision data collected at a centre-of-mass energy of √ s = 7 TeV with the LHCb detector, measurements of the polarization amplitudes, strong phase difference and triple product asymmetries in the Bs → φφ decay mode are presented. The measured values are |A0|2 = 0.365 ± 0.022 (stat) ± 0.012 (syst), |A⊥|2 = 0.291 ± 0.024 (stat) ± 0.010 (syst), cos(δ‖) = −0.844 ± 0.068 (stat) ± 0.029 (syst), AU = −0.055 ± 0.036 (stat) ± 0.018 (syst), AV = 0.010 ± 0.036 (stat) ± 0.018 (syst).
