Dependence of nucleon mass on parameters of instanton medium

TL;DR

This paper investigates how the nucleon mass and size are affected by the properties of the instanton medium, specifically the average instanton size and inter-instanton distance, under various scenarios.

Contribution

It provides a detailed analysis of the dependence of nucleon properties on instanton medium parameters, exploring different scenarios for their variation.

Findings

Nucleon mass varies with instanton size and inter-instanton distance.

The effective nucleon size is influenced by changes in the instanton medium.

Different scenarios show distinct dependencies of nucleon properties on medium parameters.

Abstract

We trace the dependence of the nucleon mass and of the effective size of the nucleon on the characteristics of the instanton medium, which are the average instanton size $\rho$ and the distance between the instantons in instanton medium R. We consider several scenario for variation of the values of $\rho$ and R.
