Implications from theb-decay measurements

Abstract

The recent measurements of the bottom-quark $b$ lifetime and the ratio $\frac{{\Gamma }_{b\to u}}{{\Gamma }_{b\to c}}$ are used to analyze the quark-mixing phenomena. We report the implications of these measurements on the Kobayashi-Maskawa angles and phase, $K_{e3\mathrm{}}$ and hyperon decays, $\mathrm{CP}$-violation parameter $\epsilon$, $t$-quark mass, $K^0\leftrightarrow {\overline{K}}^0$ transition dynamics, $B^0-{\overline{B}}^0$ mixing and $\mathrm{CP}$ violation, and nonleptonic decays and leptonic production of heavy quarks.
