This talk presents recent HERA results on the elastic and proton-dissociative production of the vector mesons rho^{0}, omega, phi$, J/\psi and Upsilon from photons in the Q^2-range between 0 and 60 GeV^2 and the negative momentum transfer squared to the proton, |t|, between 0 and 3 GeV^2. The data are compared to results from lower energy experiments and various predictions.

Abstract
This talk presents recent HERA results on the elastic and proton-dissociative production of the vector mesons rho^{0}, omega, phi$, J/\psi and Upsilon from photons in the Q^2-range between 0 and 60 GeV^2 and the negative momentum transfer squared to the proton, |t|, between 0 and 3 GeV^2. The data are compared to results from lower energy experiments and various predictions.File in questo prodotto:
