Variations of hadron masses and matter properties in dense nuclear matter
Abstract
Using a selfconsistent quark model for nuclear matter we investigate variations of the masses of the nonstrange vector mesons, the hyperons, and the nucleon in dense nuclear matter (up to four times the normal nuclear density). We find that the changes in the hadron masses can be described in terms of the value of the scalar mean field in matter. The model is then used to calculate the density dependence of the quark condensate inmedium, which turns out to be well approximated by a linear function of the nuclear density. Some relations among the hadron properties and the inmedium quark condensate are discussed.
