# Monte Carlo simulation of two-photon processes III: Complete lowest order calculations for e + e −→e + e − μ + μ − with large angle tagging conditions

## Description

Title of program: DIAG12NST Catalogue Id: AAFJ_v1_0 Nature of problem Single tagging conditions have to be applied to two-photon processes when one wants to measure the four-momentum of one of the virtual photons in the 'multiperipheral' Feynman diagrams in order to obtain information on e.g. the Q^2 dependence of the photon structure function. The program, presented here, generates unweighted events for the process e^+e^- -> e^+e^-mu^+mu^- and calculates exact total and differential cross sections on the basis of all twelve Feynman diagrams contributing in lowest orde ...
