Chiral Color Dielectric Model

The behavior of a nucleon in nuclear medium is discussed in Chiral Color Dielectric Model. It is assumed that the nucleons in nuclear medium produces a background dielectric field and the quark and dielectric field equations are solved self consistantly in presence of the dielectric field. A nucleon in nuclear medium is then constructed by means of standard procedure followed in chiral bag models. The corrections due to center of mass motion, color magnetic interaction and meson interaction are included. The calculations show that the nucleon becomes bigger in the medium but its mass does not change much. It is found that beyond a certian density, bound solutions in which quarks are bound in self-generated dielectric field are not possible. Thus, the calculations indicate that there is a critical density beyond which the matter consists of deconfined quarks.

Chiral Color Dielectric Model

The momentum projected SU(3) chiral color dielectric model (CCDM) is employed to calculate the charge root mean square radii and charge distribution of hyperons. The gluonic and pionic contributions are treated perturbatively. We compare our result with that of Skyrme, MIT bag and cloudy bag model. The charge distribution of Λ in CCDM is similar to that of Skyrme model prediction.
