Flavour tagged time dependent angular analysis of the B 0s → J/ψφ decay and extraction of ∆Γ s and the weak phase φ s in ATLAS
A measurement of the B 0s → J/ψφ decay parameters, updated to include flavour tagging, is reported using 4.9 fb−1 of integrated luminosity collected by the ATLAS detector from pp collisions recorded in 2011. A search for new physics in φs was undertaken by measuring φs , the mean lifetime Γs and the...

| Sumario: | A measurement of the B 0s → J/ψφ decay parameters, updated to include flavour tagging, is reported using 4.9 fb−1 of integrated luminosity collected by the ATLAS detector from pp collisions recorded in 2011. A search for new physics in φs was undertaken by measuring φs , the mean lifetime Γs and the lifetime difference ∆Γs. |
