Abstract

Double-tagged interactions of photons with virtualities Q^2 between 10GeV^2 and 200GeV^2 are studied with the data collected by DELPHI at LEP2 from 1998 to 2000, corresponding to an integrated luminosity of 550pb^-1. The gamma*gamma* -> mu+mu- data agree with QED predictions. The cross-section of the reaction gamma*gamma* -> hadrons is measured and compared to the LO and NLO BFKL calculations.
