Effect of Pion-Pion Scattering Resonance on Nucleon Structure and Pion-Nucleon Scattering at Low Energies
The effect of pion-pion scattering resonance on the isovector part of nucleon structure is analysed by a method similar to that of Frazer and Fulco, but with one more subtraction for dispersion relations on helicity amplitudes of nucleon·aritinucleon production process in order to remedy the divergence regarding the left-hand cut. If the subtracted spectral representations are used for the form...
متن کاملPion-Nucleon Scattering in Kadyshevsky Formalism: I Meson Exchange Sector
In a series of two papers we present the theoretical results of πN/meson-baryon scattering in the Kadyshevsky formalism. In this paper the results are given for meson exchange diagrams. On the formal side we show, by means of an example, how general couplings, i.e. couplings containing multiple derivatives and/or higher spin fields, should be treated. We do this by introducing and applying the ...
متن کاملRenormalization prescriptions in effective theory of pion-nucleon scattering
Using the results presented in the talk [1] we illustrate the approach developed in [2]–[5] by the calculation of πN elastic scattering amplitude and explain how to derive corresponding bootstrap conditions. In the end, we briefly mention some results of numerical comparison with experimental data.
متن کاملLow-energy pion-nucleon scattering
An analysis of low-energy charged pion-nucleon data from recent pp experiments is presented. From the scattering lengths and the Goldberger-Miyazawa-Oehme ~GMO! sum rule we find a value of the pion-nucleon coupling constant of f 50.075660.0007. We also find, contrary to most previous analyses, that the scattering volumes for the P31 and P13 partial waves are equal, within errors, corresponding ...
متن کاملCharm Meson Production from Meson-nucleon Scattering
Because of their large masses, one expects charm mesons to be mostly produced in the initial preequilibrium stage of relativistic heavy ion collisions. They have thus been suggested as possible probes of the initial dynamics in these collisions. Previous studies have been concentrated on the production of charm quarks from the preequilibrium partonic matter [1]. For charm meson production from ...
