Abstract (data abstract)
CERN-LEP. Measurement of the cross section for hadron production in double tagged two photon events from E+ E- interactions at centre-of-mass energies from 189 to 209 GeV. The data were collected in the period 1998 to 2000 and have an integrated luminosity of 592.9 pb-1. Both scattered electrons are detected in the small angle silicon-tungsten (SW) luminometer.
