Line-shape and asymmetries analysis on the Z peak is described. Then, the consistency of the Standard Model predictions with experimental data and consequent limits on the top mass are discussed. Finally, the possibility of extracting information and constrains on new theoretical models from present data is examined.(Invited talk at the XIV Encontro Nacional de Fis. de Campos e Part.s, Caxambu, Brasil, 29 Sept.-3 Oct. 1993), 21 pages, Latex, Roma1 preprint n.984, Dec. 1993High Energy Physics - Phenomenologytext
