Abstract
Measurements of the two-photon interaction e+e− → e+e− + hadrons at √s ⋍ 192 and √s ⋍ 183 GeV are presented. The double-tag events, collected with the L3 detector, correspond to interated luminosities of 140 pb-1 at 91 GeV and 52 pb−1 at 183 GeV. The cross-section of γ∗γ∗ collisions has been measured at ≶Q2≶ = 3.5 GeV2 and ≶Q2≶ = 14 GeV2. The data agree well with predictions based on perturbative QCD, while the Quark Parton Model alone is insufficient to describe the data.
