Abstract The program WTO, which is designed for computing cross sections and other relevant observables in the e + e − annihilation into four fermions, is described. The various quantities are computed over both a completely inclusive experimental set-up and a realistic one, i.e. with cuts on the final state energies, final state angles, scattering angles and final state invariant masses. Initial state QED corrections are included by means... Title of program: WTO Catalogue Id: ADDK_v1_0 Nature of problem An accurate description of the process e+e- -> 4 fermions is needed in order to fully describe the physics available at LEP 2 and at higher energies. In particular the properties of the W boson can be correctly analyzed around and above the threshold only when the full gauge- invariant set of diagrams contributing to a given final state is included. Similarly the Z - Z production and the Higgs boson production can be studied within the minimal standard model. Indeed from a field theoretical poin ...
