Effect of Coherent State of Quarks and Mesons on Hadron Properties in the Extended Linear Sigma Model
M. Abu-shady
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 cohere…

Chiral baryon in the coherent pair approximation
T. S. T. Aly, J. A. McNeil
We revisit the work of K. Goeke, M. Harvey, F. Grümmer, and J. N. Urbano (Phys. Rev. {\bf D37}, 754 (1988)) who considered a chiral model for the nucleon based on the linear sigma…
