Abstract

In this chapter, we discuss heavy--heavy quark currents. They have many interesting applications. Matrix elements of the vector and axial b \(\to\) c currents describe exclusive semileptonic B decays, which provide one of the ways to measure the CKM matrix element \(|V_{\text{c}\text{b}}|\). Matrix elements of the electromagnetic b- and c-currents describe \(\text{B}\bar{\text{B}}\) and \(\text{D}\bar{\text{D}}\) production in e+e- annihilation.
