Novel soft - photon analysis of pp γ below pion - production threshold
نویسندگان
چکیده
A novel soft-photon amplitude is proposed to replace the conventional Low soft-photon amplitude for nucleon-nucleon bremsstrahlung. Its derivation is guided by the standard meson-exchange model of the nucleon-nucleon interaction. This new amplitude provides a superior description of ppγ data. The predictions of this new amplitude are in close agreement with potential-model calculations, which implies that, contrary to conclusions drawn by others, off-shell effects are essentially insignificant below pion-production threshold.

The handbag contribution to γγ → ππ and KK
We investigate the soft handbag contribution to two-photon annihilation into pion or kaon pairs at large energy and momentum transfer. The amplitude is expressed as a hard γγ → q ¯ q subprocess times a form factor describing the soft transition from q ¯ q to the meson pair. We find the calculated angular dependence of the cross section in good agreement with data, and extract annihilation form ...
متن کاملDetermination of the πNN Form Factor from the Threshold Pion Production of pp Scattering
It is shown that the threshold productions of π0pp, π+np and π+d from pp collisions can be consistently described by a model consisting of a pion s-wave rescattering and NN̄ pair-terms of heavy-meson exchanges. The large difference between σ(pp → π+d) and σ(pp → π+np) is understood from the orthogonality of the deuteron and the np scattering wave functions. In a calculation using the Paris poten...
متن کاملNovel Master Formula for Twist-3 Soft-Gluon-Pole Mechanism to Single Transverse-Spin Asymmetry
We prove that twist-3 soft-gluon-pole (SGP) cross section for single spin asymmetries is determined by a certain “primordial” twist-2 cross section up to kinematic and color factors in the leading order perturbative QCD. This unveils universal structure behind the SGP cross sections in a variety of hard processes, and also the special role of the scale invariance in the corresponding primordial...
متن کاملA Microscopic Calculation of Photoabsorption Cross Sections on Protons and Nuclei
A recently developed model for ρ-meson propagation in dense hadronic matter is applied to total photoabsorption cross sections in γ-proton and γ-nucleus reactions. Within the vector dominance model the photon coupling to the virtual pion cloud of the nucleon, two-body meson-exchange currents, as well as γ-nucleon resonances are included. Whereas the γp reaction is determined by the low-density ...
متن کاملNovel approach to pion and eta production in proton-proton collisions
We evaluate the threshold matrix–element for the reaction pp → ppπ0 in a fully relativistic Feynman diagrammatic approach. We employ a simple effective range approximation to take care of the S–wave pp final–state interaction. The experimental value for the threshold amplitude A = (2.7− i 0.3) fm4 can be reproduced by contributions from tree level chiral (long–range) pion exchange and short–ran...
