Experimental status and prospects of flavour mixing and CP violation

The mixing of quarks through the weak interaction is described by a unitary matrix which can be parametrized in terms of three angles and one phase. Experimental results on weak decays of hyperons and B mesons, on neutrino production of charm quarks, and on the B meson lifetime are used to obtain, in a combined fit, values for the three mixing angles in the Kobayashi-Maskawa scheme: sin theta1=0.231 +- 0.003, 0.025 < sin theta2 < 0.06 and sin theta3 +- 0.02. In the Maiani parametrization, the angles obtained are: sin theta=0.231 +- 0.003, vertical strokesin γvertical stroke=0.044 (+0.007 -0.005) and sin β < 0.004. Future prospects for experiments on flavour mixing and CP violation are discussed. (orig.)
