Abstract
Using 1.0 fb 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 Bs0→ϕϕ decay mode are presented. The measured values are|=0.365±0.022(stat)±0.012(syst),|=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).File in questo prodotto:
