Abstract.We present an up-to-date profile of the Cabibbo-Kobayashi-Maskawa matrix with emphasis on the interpretation of recent CP-violation results from the B factories. For this purpose, we review all relevant experimental and theoretical inputs from the contributing domains of electroweak interaction. We give the “standard” determination of the apex of the Unitarity Triangle, namely the Wolfenstein parameters $\overline\rho$ and $\overline\eta$, by means of a global CKM fit. The fit is…

To show how new physics may give very different results, this work looks at the predictions of a simple model where both the standard model and superweak contributions to the K 0 and B 0 mass matrices coexist and finds that practically any values are allowed for the asymmetries.

This work studies the success to describe hyperon semileptonic decays of four models that incorporate second-order SU(3) symmetry breaking corrections and concludes that only the model whose corrections are O(m_s) and O( m_s^{3/2}) is successful.
