Total Hadronic Cross-Section for Photon-Photon Interactions at LEP
The total hadronic cross-section for the interaction of real photons is extracted from a measurement of the cross-section of the process e+e->e+e- + hadrons using a luminosity function for the photon flux and form factors for extrapolating to Q**2=0. The data was taken with the OPAL detector at L...

| Sumario: | The total hadronic cross-section for the interaction of real photons is extracted from a measurement of the cross-section of the process e+e->e+e- + hadrons using a luminosity function for the photon flux and form factors for extrapolating to Q**2=0. The data was taken with the OPAL detector at LEP at e+e- centre-of-mass energies of 161 GeV and 172 GeV. In the energy range 10 < W < 110 GeV the total hadronic photon-photon cross-section is consistent with the Regge behaviour of the total cross-section observed in \gamma p and hadron-hadron interactions. |
