We develop the color dipole phenomenology of diffractive photo- and electroproduction $\gamma^{*}\,N\rightarrow V(V')\,N$ of light vector mesons ($V(1S) = \phi^0, \omega^0, \rho^0$) and their radial excitations ($V'(2S) = \phi', \omega',…
We calculate diffractive photo- and leptoproduction of $\rho$-, $\rho'$- and $\rho''$-mesons. The incoming photon dissociates into a $q\bar{q}$-dipole which scatters on the nucleon and transforms into a vector meson state. The scattering…
