Magnetic moment and radius of the nucleon in a nonlocal model of meson-nucleon interaction
Magnetic moment and radius of the nucleon are calculated in a nonlocal extension of the chiral linear σ−model. Properties of the nonlocal model under the vector and axial transformations are considered. The conserved electromagnetic and vector currents, and partially conserved axial vector current are obtained. In the calculation of the nucleon electromagnetic vertex the π− and σ−loop diagrams ...
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 کاملA Covariant Meson-Nucleon Equation
The integration is carried out in the reference frame in which the spatial components of P, are zero and the dimensionless quantities cr = l4/222 and c=Fp/m are introduced. The real part of 8M is obtained by straightforward integration with absolute value signs placed on the argument of the logarithm: Re 5M = (3g2/162r2) m( —1+2n2+ (1+3422 2c24+ (422—1)/e') in~+ ccp (2422—7) (4—c22)—*' Xtan-'a(...
متن کاملMeson Clouds and Nucleon Electromagnetic Form Factors
In contrast with common non-relativistic lore, the usual Sachs form factors are not the Fourier transforms of charge or magnetization densities. Instead, the two-dimensional Fourier transform of the electromagnetic F1 form factor is the charge charge density of partons in the transverse plane. An analysis of the available data for neutron form factors leads to the result that the neutron charge...
متن کاملThe Nucleon-Nucleon Interaction
Recent developements in our understanding of the fundamental nucleon-nucleon interaction are reviewed. Among the topics considered are (1) the so-called high-precision nucleon-nucleon potentials that emerged in the mid 1990s, (2) progress in the microscopic description of the intermediate-range part of the nucleon-nucleon interaction in terms of correlated pion-pion and rho-pion exchange and (3...
