Abstract SMATASY is an interface for the ZFITTER package and may be used for the model independent description of the Z resonance at LEP 1 and SLC. It allows the determination of the Z mass and width and its resonance shape parameters r and j for cross-sections and their asymmetries. The r describes the peak height and j the interference of the Z resonance with photon exchange in each scattering channel and for σ_T , σ_(FB), σ_(lr), σ_(pol)etc. separately. Alternatively, the helicity amplitudes... Title of program: SMATASY version 2.2 Catalogue Id: ADBG_v1_0 Nature of problem The program determines cross sections and asymmetries in the vicinity of the Z resonance taking into account radiative corrections up to O(alpha^2). This model independent determination is based on the S-matrix approach.
