We study the hard exclusive production of two pions in the virtual photon fragmentation region with various invariant masses including the resonance region. The amplitude is expressed in terms of two-pion light-cone distribution amplitudes (2πDA’s). We derive dispersion relations for these amplitudes, which allow to fix them completely in terms of ππ-scattering phases and a few low-energy subtraction constants determined by the effective chiral Lagrangian. Quantitative estimates of the resonance as well ππ background DA’s at low normalization point are made. We also prove a new soft-pion theorem relating two-pion DA’s to the one-pion DA’s. Crossing relations between 2πDA’s and parton distributions in a pion are discussed. We demontrate that...
