Indirect Determination of the Vertex and Angles of the Unitarity Triangle

The values of the elements of the Cabibbo-Kobayashi-Maskawa matrix are constrained by direct and indirect measurements. A fit to experimental data and theory calculations allows the indirect determination of the vertex and angles of the unitarity triangle as: rho = 0.18 +/- 0.07 eta = 0.35 +/- 0.05...

description The values of the elements of the Cabibbo-Kobayashi-Maskawa matrix are constrained by direct and indirect measurements. A fit to experimental data and theory calculations allows the indirect determination of the vertex and angles of the unitarity triangle as: rho = 0.18 +/- 0.07 eta = 0.35 +/- 0.05 sin 2alpha = 0.14 +0.25 -0.38 sin 2beta = 0.73 +/- 0.07 gamma = 63 +8 -11 degrees. Information is derived on the presence of CP violation in the matrix, on non-perturbative QCD parameters and on the Bs oscillation frequency.
