Quasi-real photon approximation for describing electroproduction processes
V. N. BAIER and V. S. FADINNuclear Physics Institute, Novosibirsk (USSR)
Abstract
A general approach is formulated for describing two-photon electroproduction processes (e± e- → e± e- + N) under conditions when only particles produced with a small total transverse momentum are observed. It is shown that in this case a number of amplitude combinations for the γ + γ → N process can in principle be determined, one of them being the cross section for the nonpolarized photon photoprocess ; the others enter the cross section for the photoprocess involving linearly polarized photons.
