GRAPE-Dilepton (Version 1.1) A generator for dilepton production in ep collisions
Description
Abstract GRAPE-Dilepton is a Monte Carlo event generator for dilepton production in ep collisions. The cross-section calculation is based on the exact matrix elements in the electroweak theory at tree level. The dilepton productions via γγ, γZ^0 , Z^0 Z^0collisions and via photon internal conversion are taken into account. In addition, the effects of the Z^0on/off-shell production are also included. The relevant Feynman amplitudes are generated by the automatic calculation system GRACE. The calcul...
