چکیده
σ L /σ T in the ρ 0-meson diffractive electroproproduction. Abstract The background due to the direct diffractive dissociation of the photon into the π + π −-pair to the " elastic " diffractive ρ 0-meson production in electron-proton collisions is calculated. At large Q 2 the interference between resonant and non-resonant π + π − production changes the σ L /σ T ratio with the mass of the 2π (i.e. ρ 0-meson) state.
