Abstract A computer program ee4fγ for calculating cross-sections of any four fermion final state of e^+ e^- -annihilation at high energy and the corresponding bremsstrahlung reaction that is possible in the framework of the Standard Model is presented. As the fermion masses are arbitrary, the cross-sections for channels that do not contain e^+and/or e ^-in the final state can be computed without any collinear cut, the on-shell top quark production can be studied and the Higgs boson exchange can be... Title of program: ee4fγ Catalogue Id: ADTQ_v1_0 Nature of problem Description of all e + e - -> 4 fermions and corresponding bremsstrahlung reactions that are possible in the Standard Model (SM) to lowest order and with nonzero fermion masses at center of mass energies typical for next generation linear colliders. Such reactions are relevant, typically, for W-pair or intermediate mass Higgs boson production and decay.
