The yukawa potential can be derived as the lowest order amplitude of the interaction of a pair of fermions. Ion sphere model for yukawa systems dusty plasmas s. The first born approximation consists then of approximating the scattered wave function.

Pdf scaling behavior of the yukawa potential in two and. Infatti, a differenza dell interazione elettromagnetica che agisce a lunga distanza, linterazione nucleare agisce solo allorche le particelle sono poste a distanza. In particle physics, yukawa s interaction or yukawa coupling, named after hideki yukawa, is an interaction between a scalar field. Pdf analysis of the yukawa gravitational potential in f. Yukawa potential article about yukawa potential by the. Despite its successes, the fundamental nature of dark matter and dark energy is still unknown. Consider the electrostatic potential about a charged point particle. The yukawa potential is used to model interparticle interactions in plasmas, dusty plasmas, colloidal suspensions, and atomic physics. The constant g2 tells us about the depth of the potential, or the size of the force.

Glassy dynamics in the potential energy landscape p. This approximation corresponds to the first iteration in the born series of 1. Alternative theories of gravity may serve to overcame several shortcomings of the standard cosmological model but, in their weak field limit, they must recover general relativity to match the tight constraints at solar system scale.

Indeed, in highenergy physics, we learn that all interactions are due to the exchange of virtual nonenergy conserving gauge bosons, e. The notion of an interparticle potential is therefore an approximation that neglects. The born approximation yields 1267 thus, is proportional to the fourier transform of the scattering potential with respect to the wavevector. This describes the potential for a force mediated by massless particles, the photons.
