Abstract

Ten three-body processes ine+e−collisions for heavy particle productions such as Higgs, t-quark,W±andZ0are calculated by two independent computer codes for automatic calculation of Feynman amplitude. The results are in excellent agreement within statistical error of numerical integration (about 0.5%). This demonstrates that these systems are quite powerful for theoretical study for futuree+e−,e±γand γγ colliders. Numerical values of cross sections are summarized in tables and a figure.
