A study of one-prong Tau decays with a charged kaon

Abstract

Abstract. From an analysis of the ionisation energy loss of charged particles selected from 110326 $${\rm e}^+{\rm e}^- \rightarrow \tau^+\tau^-$$ candidates recorded by the OPAL detector at $${\rm e}^+{\rm e}^-$$ centre-of-mass energies near the Z$$^0$$ resonance, we determine the one-prong tau decay branching ratios:\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}\begin{eqnarray*} {\rm Br}(\tau^- \rightarrow \nu_\tau{\rm K}^- \ge ..
