dc.description.abstractA key ingredient to searches for physics beyond the Standard Model in B0s mixing phenomena is the measurement of the B0s – B0 s oscillation frequency, which is equivalent to the mass difference 1ms of the B0s mass eigenstates. Using the world’s largest B0s meson sample accumulated in a dataset, corresponding to an integrated luminosity of 1.0 fb−1, collected by the LHCb experiment at the CERN LHC in 2011, a measurement of 1ms is presented. A total of about 34 000B0s !D− s + signal decays are reconstructed, with an average decay time resolution of 44 fs. The oscillation frequency is measured to be 1ms = 17.768± 0.023 (stat) ±0.006 (syst) ps−1, which is the most precise measurement to dategl
