dc.description.abstractWe present a measurement of the C P -violating weak mixing phase ϕ s using the decay ¯ B 0 s → D + s D − s in a data sample corresponding to 3.0   fb − 1 of integrated luminosity collected with the LHCb detector in p p collisions at center-of-mass energies of 7 and 8 TeV. An analysis of the time evolution of the system, which does not use the constraint | λ | = 1 to allow for the presence of C P violation in decay, yields ϕ s = 0.02 ± 0.17 ( stat ) ± 0.02 ( syst )     rad , | λ | = 0.91 + 0.18 − 0.15 ( stat ) ± 0.02 ( syst ) . This result is consistent with the standard model expectation.
