| dc.description | The backgrounds due to the direct diffractive dissociation of the photon into the $π^+π^-$ as well as $K^+K^-$ pairs to the "elastic" diffractive $ρ'$ and $ϕ$ mesons production in electron-proton collisions are calculated. It is shown that the role of background and background-resonant interference contributions is very important in experimental distribution of $M_{π^+ π^-}$ in the $ρ'$ mass region. The amplitude for the background process is proportional to the $π$-meson - proton or K-meson - proton cross sections. Therefore, describing the HERA data, one can estimate $σ(πp)$ and $σ(Kp)$ at energies higher than the region of direct measurements. | |
