摘要
The reaction e+e- → e+e-γ*γ* → e+e-hadrons for quasi-real photons is studied using data from √s = 183 GeV up to 202 GeV. Results on the total cross sections σ(e+e- → e+e-hadrons) and σ(γγ → hadrons) are given for the two-photon centre-of-mass energies 5 GeV ≤ Wγγ ≤ 185 GeV. The total cross section of two real photons is described by a Regge parametrisation. We observe a steeper rise with the two-photon centre-of-mass energy as compared to the hadron-hadron and the photon-proton cross sections. The data are also compared to the expectations of different theoretical models.
