Abstract
Ten three-body processes in e(+) e(-) collisions for heavy particle pr oductions such as Higgs, t-quark, W+/- and Z(0) are calculated by two independent computer codes for automatic calculation of Feynman amplit ude. The results are in excellent agreement within statisi tical error of numerical integration (about 0.5%). This demonstrates that these s ystems are quite powerful for theoretical study for future e(+) e(-), e+/-gamma and gamma gamma colliders. Numerical values of cross section s are summarized in tables and a figure.
