Semiclassical description of exclusive meson pair production in gamma*gamma scattering - art. no. 036003

A semiclassical picture is given for the production of exclusive meson pair s in gamma*gamma scattering using elements of the Lund string fragmentation model, spin and C-parity conservation. The model can be generalized to the production of any few meson states in scattering reactions at intermediate momentum transfers. As an example we show that we get a consistent descrip tion for the time-like pion form factor. For the reaction gamma*gamma-->pi (+)pi (-) we find a sizable cross section at CERN LEP2 energies.
