Abstract

Exclusive ρ0ρ0ρ0ρ0 production in two-photon collisions between a quasi-real and a mid-virtuality photon is studied with data collected at LEP at centre-of-mass energies 183<209 GeV with a total integrated luminosity of 684.8 pb−1. The cross section of the process γγ*→ρ0ρ0 is determined as a function of the photon virtuality, Q2, and the two-photon centre-of-mass energy, WγγWγγ, in the kinematic region: 0.2<0.85 GeV2 and 1.1<3 GeV.
