摘要：

A chiral quark soliton model for the baryon embedded in nuclear medium is proposed. The effective vacuum expectation value of the scalar field felt up by a quark of the baryon in nuclear medium is estimated. The model is solved for the hedgehog baryon state in the semiclassical approximation and self-consistent approach. Some static properties of the baryon embedded in nuclear medium are calculated. An increment in radius of the baryon is obtained. The numerical results can be used to explain the A-dependence of EMC effect and vacuum pressure constants in nuclear medium.
