First determination of the quark mixing matrix element Vtb independent of assumptions of unitarity

Abstract

We present a new method for the determination of the Cabibbo-Kobayashi-Maskawa quark mixing matrix element $|V_{tb}|$ from electroweak loop corrections, in particular those affecting the process $Z\to b\bar{b}$. From a combined analysis of results from the LEP, SLC, Tevatron, and neutrino scattering experiments we determine $|V_{tb}|=0.77_{-0.24}^{+0.18}$. This is the first determination of $|V_{tb}|$ which is independent of unitarity assumptions.
