Jet Production in Photon-Photon Interactions

We present results on jet production in γγ interactions where both photons are quasi-real. The invariant masses of the hadronnic system are limited to the range 4≦Wvis≦12 GeV/c2. The data approach the quark-Parton-Model (QPM) expectation at the highestp T jet values (≧4 GeV/c). Jet production at lowp T (≦1 GeV/c) can be described by a Vector Dominance derived model. The data also have a component with no apparent jet structure in the range, 1.0 ≦P T jet ≦4.0 GeV/c which can be described by phase space or by models of the QCD hard scattering processes cesses\(\gamma \gamma \to q\bar qg\) and\(\gamma \gamma \to q\bar qq\bar q\)
