Semi-classical Description of Exclusive Meson Pair Production in ${\gamma }^{\ast }\gamma$ Scattering

Abstract

A semi-classical picture is given for the production of exclusive meson pairs in γγ^* 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 description for the time-like pion form factor. For the reaction γγ^*\to π^+π^- we find a seizable cross section at LEP2 energies.
