Abstract

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 B0s → φ φ 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), A_U = −0.055 ± 0.036(stat) ± 0.018(syst), A_V = 0.010 ± 0.036(stat) ± 0.018(syst).
