Abstract

Using 1.0fb -1 of pp collision data collected at a centre-of-mass energy of √s=7TeV with the LHCb detector, measurements of the polarization amplitudes, strong phase difference and triple product asymmetries in the B s0→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). © 2012 CERN.
