TL;DR
In the course of the investigations, the analysis of the unitarity triangle is extended beyond the leading order in \lambda and several useful analytic formulae for quantities of interest are derived.
Abstract
Anticipating improved determinations of mt, | Vub/Vcb |, BK and FB BB in the next five years we make an excursion in the future in order to find a possible picture of the unitarity triangle, of quark mixing and of CP-violation around the year 2000. We then analyse what impact on this picture will have the measurements of four possibly cleanest quantities: BR(K + → π + ν¯ν), xd/xs, sin(2α) and sin(2β). Our analysis shows very clearly that there is an exciting time ahead of us. In the course of our investigations we extend the analysis of the unitarity triangle beyond the leading order in λ and we derive several useful analytic formulae for quantities of interest.

The present set of constraints on the parameters of the standard model are examined and the unitarity triangle is used to present their allowed range, emphasizing what luminosity of an electron-positron collider is needed to guarantee a statistically significant asymmetry in one or more {ital B} decay channels.

It is shown how relations among various classes of {ital CP} asymmetries in {ital B}{sup 0} decays can be used to test the unitarity of the three-generation Cabibbo-Kobayashi-Maskawa matrix, independently of the mechanism of mixing in the{ital B} and {ital K}{Sup 0} systems.
