Abstract

The B0-B̄0 oscillation frequency δm<inf>d</inf> is measured by the LHCb experiment using a dataset corresponding to an integrated luminosity of 1.0fb^-1 of proton-proton collisions at √s=7TeV, and is found to be δm<inf>d</inf>=0.5156±0.0051(stat.)±0.0033(syst.)ps^-1. The measurement is based on results from analyses of the decays B⁰→D^-π⁺ (D^-→K⁺π^-π^-) and B⁰→J/ψK^*0 (J/ψ→μ⁺μ^-, K^*0→K⁺π^-) and their charge conjugated modes. © 2013 CERN.
