Quarkmeson coupling model for a nucleon
Abstract
We considered the quarkmeson coupling model for a nucleon. The model describes a nucleon as an MIT bag, in which quarks are coupled to the scalar and the vector mesons. A set of coupled equations for the quark and the meson fields are obtained and are solved in a selfconsistent manner. We show that the mass of a dressed MIT bag interacting with $\sigma$ and $\omega$meson fields differs considerably from the mass of the free MIT bag. The effects of the densitydependent bag constant are investigated. The results of our calculations imply that the selfenergy of the bag in the quarkmeson coupling model is significant and needs to be considered in doing the calculations for nuclear matter or finite nuclei.
