Diffractive photo- and leptoproduction of vector mesons $\rho$, ${\rho }^{\prime }$ and ${\rho }^{\prime \prime }$

G. Kulzinger, H. G. Dosch, H. J. Pirner

We calculate diffractive photo- and leptoproduction of $\rho$-, ${\rho }^{\prime }$- and ${\rho }^{\prime \prime }$-mesons. The incoming photon dissociates into a $q\bar{q}$-dipole which scatters on the nucleon and tran…
