A unitary model for meson-nucleon scattering
In an effective Lagrangian model employing the K-matrix approximation we extract nucleon resonance parameters. To this end we analyze simultaneously all available data for reactions involving the final states πN , ππN , ηN and KΛ in the energy range mN + mπ ≤ √ s ≤ 1.9 GeV. The background contributions are generated consistently from the relevant Feynman amplitudes, thus significantly reducing ...
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 ...
متن کاملChiral unitary meson–baryon dynamics in the presence of resonances: Elastic pion–nucleon scattering
We develop a novel approach to chiral meson–baryon dynamics incorporating unitarity constraints and explicit resonance fields. It is based on the most general structure of any pion-nucleon partial wave amplitude neglecting the unphysical cuts as derived from theN/D method. This amplitude is then matched to the one–loop heavy baryon chiral perturbation theory result at third order and to tree le...
متن کاملNucleon Resonances in Meson Nucleon Scattering with Strangeness Production
An effective Lagrangian model in a coupled channels framework is applied to extract nucleon resonance parameters. In the K-matrix approximation, we simultaneously analyze all the available data for the transitions from πN to five possible meson-baryon final states, πN, ππN, ηN,KΛ, and KΣ, in the energy range from πN threshold up to √ s = 2 GeV. In this work, we focus our efforts on the KΣ chann...
متن کاملQuark-Meson Coupling Model for a Nucleon
We considered the quark-meson coupling model for a nucleon. The model describes a nucleon as an MIT bag, in which quarks are coupled to the scalar and the vector mesons. A set of coupled equations for the quark and the meson fields are obtained and are solved in a self-consistent manner. We show that the mass of a dressed MIT bag interacting with σand ω-meson fields differs considerably from th...
