Abstract
Using 1.0 fb−1 of pp collision data collected at a centre-of-mass energy of with the LHCb detector, measurements of the polarization amplitudes, strong phase difference and triple product asymmetries in the 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).
