Diffractive large transferred momentum photoproduction of vector mesons
A. Ivanov, R. Kirschner
Abstract
The large t behaviour of the helicity amplitudes of diffractive photoproduction is estimated relying on models of the photon and meson light-cone wave functions and on the double-logarithmic approximation to the exchanged gluon interaction. The role of large-size colour dipole contributions to the photon-meson transition impact factor is discussed.
