Measurement of Exclusive rho0 rho0 Production in Two-Photon Collisions at High Q2 at LEP
L3 Collaboration
Abstract
Exclusive rho rho production in two-photon collisions involving a single highly virtual photon is studied with data collected at LEP at centre-of-mass energies 89GeV < s < 209GeV with a total integrated luminosity of 854.7pb-1 The cross section of the process gamma gamma* -> rho rho is determined as a function of the photon virtuality, Q2 and the two-photon centre-of-mass energy, Wgg, in the kinematic region: 1.2GeV2 < Q2 < 30GeV2 and 1.1GeV < Wgg < 3GeV.
