Abstract
We compute the order-alpha (s) corrections to the total cross section and t o jet rates for the process e(+)e(-) --> e(+)e(-) hadrons, where the hadron s are produced through crossed-channel quark exchange in the hard scatterin g of two off-shell photons originating from the incoming leptons. We use a next-to-leading order general-purpose partonic Monte Carlo event generator that allows the computation of a rate differential in the produced leptons and hadrons. We compare our results with the available experimental data fo r e(+)e(-) --> e(+)e(-) + hadrons at LEP2.
