    ABSTRACT: Formulae are presented by which a numerically stable computer program for two-photon processes above can be constructed. For this purpose a new method for evaluating matrix elements is introduced. It is then shown that two-photon processes should be no background to Drell-Yan signals in pp collisions. A comparison is made between two-photon physics at e+e−, ep and pp collisions.
