Abstract

An analysis of gamma gamma interactions has been performed using untagged hadronic data obtained by the ALEPH detector at LEP. The data at low transverse momentum (p(t)) are well reproduced by a model based on the vector meson dominance mechanism (VDM). At high p(t)thrust the presence of hard scattering processes is demonstrated. This component is well described in shape and normalization by a QCD calculation.
