Effect of Coherent State of Quarks and Mesons on Hadron Properties in the Extended Linear Sigma Model

Abstract

The extended chiral sigma model with quark fields and elementary pion and sigma fields is used to describe static nucleon properties. The field equations have been solved in coherent pair approximation. Better results are obtained for nucleon properties in comparison with previous work and reasonably agree with data.
