A Minimal Relativistic Model for the Three Nucleon System*
. A start is made on disentangling relativistic kinematic effects from “three body forces” by presenting a minimal relativistic model in which the internal mesonic degree of freedom is treated on the same footing as the nucleonic degrees of freedom. The meson is not allowed to appear asymptotically, specifying the two-nucleon “off shell” amplitudes which can be used to calculate the three nucle...
متن کاملNucleon Form Factors in a Relativistic Three-quark Model
We report the calculation of electromagnetic form factors of nucleons within a relativistic three-quark model with Gaussian shape for the nucleon-quark vertex. The allowed region for two adjustable parameters, the range parameter ΛN in the Gaussian and the constituent quark mass mq, is obtained from fitting the data for magnetic moments and electromagnetic radii of nucleons. It is found that th...
متن کاملNucleon generalized polarizabilities within a relativistic Constituent Quark Model
Nucleon generalized polarizabilities are investigated within a relativistic framework, defining such quantities through a Lorentz covariant multipole expansion of the amplitude for virtual Compton scattering. The key physical ingredients in the calculation of the nucleon polarizabilities are the Lorentz invariant reduced matrix elements of the electromagnetic transition current, which can be ev...

A relativistic two-nucleon model for A(p, K +) Λ B reaction Abstract We investigate the A(p, K +) Λ B reaction within a covariant two nucleon model. We focus on amplitudes which are described by creation, propagation and decay into relevant channel of N * (1650), N * (1710), and N * (1720) intermediate baryonic resonance states in the initial collision of the projectile nucleon with one of its ...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
