| dc.description | The eta_c-gamma transition form factor is calculated in a model based on a modified hard scattering approach to exclusive reactions, in which transverse degrees of freedom are taken into account. For the eta_c-meson a distribution amplitude of the Bauer-Stech-Wirbel type is used, where the two free parameters, namely the decay constant f(eta_c) and the transverse size of the wave function, are related to the Fock state probability and the width for the two-photon decay Gamma[eta_c -> gamma gamma]. | |
