Flavour physics at LHCb

Abstract

Some selected results of the LHCb experiment, running at the LHC with pp collisions at 7 TeV and 8 TeV, are reported here, after operation with a total integrated luminosity of 3.0 fb−1 (Run 1). We focus on the most recent analyses on flavour physics, that include measurements of the CKM invariant phases γ and β, precision determination of the quark coupling strength Vub, observation of the very rare decays B0 (s) → μ+μ−, search for new physics in the anomalous branching ratio of B → D∗τν¯, and precision angular analysis of the rare decays B0 → K∗0μ+μ− and B0 s → φμ+μ−. Detailed comparisons are performed in all cases with the predictions of the Standard Model, and a few interesting tensions are observed.
