LHCb Constraints on the Unitarity Triangle

The consistency of measurements of the sides and angles of the CKM Unitarity Triangle provides powerful tests of the Standard Model. The LHCb experiment at the CERN Large Hadron Collider has reported several measurements that improve the sensitivity of these tests. We report the status and prospects of such measurements, including results on the angles $\gamma$, $ \beta$ and $\phi_s$ and on the oscillation frequencies $\Delta m_s$ and$ \Delta m_d$.
