Multiple Hard Interactions in Gamma-Gamma and Gamma-P Physics at LEP and HERA

J. M. Butterworth, J. R. Forshaw, M. H. Seymour +2

At $e^{+}{e}^{-}$ and $ep$ colliders, the large fluxes of almost on-shell photons accompanying the lepton beams lead to the photoproduction of jets. As the centre-of-mass energy is incre…
