Abstract
We give here the total cross sections for the following three high-energy processes: (i) γ+γ→e++e++e-+e-, (ii) γ+γ→π ++π++π-+π-, and (iii) γ+γ→π++π-+e++e-. Up to the eighth order, all of them approach constants in the high-energy limit. These constants are 6.5, 0.23×10-5, and 0.26×10-3 μb, respectively, for (i), (ii), and (iii). The corresponding photon-photon elastic scattering amplitudes in the forward direction are also given. The creation of μ pairs is also briefly discussed. © 1970 The American Physical Society.
