Abstract

The B0s–anti-B0s oscillation frequency Δms is measured with 36 pb^−1 of data collected in pp collisions at √s = 7 TeV by the LHCb experiment at the Large Hadron Collider. A total of 1381 B0s → Ds− π+ and B0s → Ds− π+ π− π+ signal decays are reconstructed, with average decay time resolutions of 44 fs and 36 fs, respectively. An oscillation signal with a statistical significance of 4.6σ is observed. The measured oscillation frequency is Δms = 17.63 ± 0.11(stat) ± 0.02(syst) ps^−1.
