Abstract

Using 1.0 fb(-1) of pp collision data collected at a centre-of-mass energy of root s = 7 TeV with the LHCb detector, measurements of the polarization amplitudes, strong phase difference and triple product asymmetries in the B-s(0) -> phi phi decay mode are presented. The measured values are vertical bar A(0)vertical bar(2) = 0.365 +/- 0.022 (stat) +/- 0.012 (syst), vertical bar A(perpendicular to)vertical bar(2) = 0.291 +/- 0.024 (stat) +/- 0.010 (syst), cos(delta(parallel to)) = -0.844 +/- 0.068 (stat) +/- 0.029 (syst), A(U) = -0.055 +/- 0.036 (stat) +/- 0.018 (syst), A(V) = 0.010 +/- 0.036 (stat) +/- 0.018 (syst).
