چکیده
Based on a prior model on double pion photoproduction on the proton, successfully tested in total cross sections and invariant mass distributions, we make a theoretical study of the angular dependence of helicity asymmetries from the interaction of circularly polarized photons with unpolarized protons. We show that this observable is sensitive to details of the internal mechanisms and, thus, represents a complementary test of the theoretical model.

Recent information on invariant mass distributions of the γp → π + π 0 n reaction, where previous theoretical models had shown deficiencies , have made more evident the need for new mechanisms, so far neglected or inaccurately included. We have updated a previous model to include new necessary mechanisms. We find that the production of the ρ meson, and the ∆(1700) excitation, through interferen...

Pion photo-and electroproduction has been studied at threshold and in the resonance region below W < 2 GeV. At threshold π 0 production can be very well explained within a dynamical model derived from an effective chiral Lagrangian. The final state interaction is nearly saturated by single charge exchange rescattering. In the resonance region new electroproduction data at Q 2 = 1 GeV 2 has been...

We present predictions for n(γ,K)Σ differential cross sections and photonbeam asymmetries and compare them to recent LEPS data. We adapt a Reggeplus-resonance (RPR) model developed to describe photoinduced and electroinduced kaon production off protons. The non-resonant contributions to the amplitude are modelled in terms of K(494) and K(892) Regge-trajectory exchange. This amplitude is supplem...

Tensor analyzing powers in forward angle exclusive π-meson photoproduction on deuteron. Abstract The target tensor analyzing powers of the process γd → π − pp had been studied in the plane wave impulse approximation, if both ejected protons are detected in coincidence and in the directions, symmetrical respect to the incoming photon momentum , being in the proton plane. The matrix elements of t...
