Measurement of CP violation parameters and polarisation fractions in B[subscript s][superscript 0] → J/ψ[¯ over K][superscript ∗ 0] decays
The first measurement of CP asymmetries in the decay (Formula Presented.) and an updated measurement of its branching fraction and polarisation fractions are presented. The results are obtained using data corresponding to an integrated luminosity of 3.0 fb[superscript −1] of proton-proton collisions...

| description | The first measurement of CP asymmetries in the decay (Formula Presented.) and an updated measurement of its branching fraction and polarisation fractions are presented. The results are obtained using data corresponding to an integrated luminosity of 3.0 fb[superscript −1] of proton-proton collisions recorded with the LHCb detector at centre-of-mass energies of 7 and 8 TeV. Together with constraints from B[superscript 0] → J/ψ ρ[superscript 0], the results are used to constrain additional contributions due to penguin diagrams in the CP -violating phase ϕ[subscript s], measured through B[subscript s][superscript 0] decays to charmonium. |
