| Abstract | ||
| The electroproduction of phi meson is analyzed. The amplitude consist of two terms, the soft and the hard pomeron terms. it is assumed, that both pomerons are Regge poles. In the present approach, the two pomeron amplitude for the photoproduction processes is extended to construct an amplitude for the electroproduction processes by introducing the photon virtual mass ( . The residues of the two poles become functions of ( . These functions are extracted by fitting the differential cross section ( ) of the extended model at constant energy to the experimental data using the chi- square method. At each , the hard and the soft terms are multiplied by the factors and to match the data. The vertices of the pomeron coupling to the interacting particles are calculated by the dimensions of the vertices which are related to the masses of the interacting particles at each vertex. | ||
