Description
Medium modification of nucleon properties are studied in the framework of the Linear Sigma Model (LSM). The nucleon is described as a chiral soliton with 3-quarks bounded due to their interactions with sigma and pion fields. Medium effects are introduced through the coupling of the quarks to sigma and omega fields, the strengths of which are determined self-consistently in a Walecka-like model, whose fermionic nucleon mass is calculated in the framework of the LSM. The nucleon properties are presented as functions of the nuclear density
