Born order study of gamma*gamma* -> rho rho at very high energy
Abstract
We calculate the cross-section for the diffractive exclusive process gamma*L (Q12) gamma*L(Q22) -> rho0L rho0L, in view of its study in the future high energy e+e- linear collider. The Born order approximation of the amplitude is completely calculable in the hard region Q1, Q2 >> LambdaQCD. The resulting cross-section is large enough for this process to be measurable with foreseen luminosity and energy, for Q1 and Q2 in the range of a few GeV.
