AB A key ingredient to searches for physics beyond the Standard Modelin B0smixing phenomena is the measurement of the B0s– B0s oscillation frequency,which is equivalent to the mass difference 1ms of the B0smass eigenstates. Usingthe world’s largest B0smeson sample accumulated in a dataset, correspondingto an integrated luminosity of 1.0 fb−1, collected by the LHCb experiment atthe CERN LHC in 2011, a measurement of 1ms is presented. A total of about34 000B0s!D−s  + signal decays are reconstructed, with an average decay timeresolution 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 date
