Exclusive two ρ0-mesons production in γγ* collision

We give a theoretical description of the L3 Collaboration data on the cross-section of the exclusive two ρ-mesons production in γγ* collision with large photon virtuality. These data prove the scaling behaviour of the leading twist generalized distribution amplitude of vector mesons. They thus prove the relevance of a partonic description of the exclusive process γγ* → ρ0ρ0 at Q2 ≥ 1.2 GeV2 and W ≤ 3.0 GeV
