Two-photon production processes at high energy. II

Abstract

We discuss the production of pairs of heavy leptons and pairs of heavy spinless mesons in ${e}^{+}{e}^{\ensuremath{-}}$ colliding beams. The two-photon production cross section of these particles is large in the energy region covered by the new machines at DESY and SLAC, and competes favorably with the one-photon production cross section. Leptonic decays of the new particles are incorporated in the analysis. We present both total cross sections and distributions in several important variables. Backgrounds from the regular two photon reaction ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ are also discussed.
