Combined measurements of the 4 LEP collaborations for the fermion pair processes \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}${\mathrm e}^{+}{\mathrm e}^{-}{\rightarrow}{\mathrm f}\overline{\mathrm f}$\end{document} are presented. The results show no significant deviations when compared with the Standard Model predictions and are used to set limits on contact interactions, Z′ gauge bosons and low scale gravity models with large extra dimensions.
