The B0s–B0soscillation frequency msis measured with 36 pb−1of data collected inppcollisions at √s=7 TeV by the LHCb experiment at the Large Hadron Collider. A total of 1381B0s→D−sπ+andB0s→D−sπ+π−π+signal decays are reconstructed, with average decay time resolutions of 44 fs and36 fs, respectively. An oscillation signal with a statistical significance of 4.6σis observed. The measuredoscillation frequency is ms=17.63±0.11(stat)±0.02(syst)ps−1.
