Abstract
At present time when a new generation of TeV colliders are beginning to
operate one needs to calculate cross-sections for a great number of various
reactions. Such calculations are united in the framework of the collider
physical program, providing definite predictions how to detect the
signatures of the new physics and separate them from the background. The
CompHEP package was created for calculation of decay and high energy
collision processes of elementary particles in the lowest order (tree)
approximation. The main idea put into the CompHEP was to make available
passing from the Lagrangian to the final distributions effectively with the
high level of automatization what is extremely needed in collider physics.
