Baryonic matter and the medium modification of the baryon masses

초록

We investigate the properties of baryonic matter within the framework of the in-medium modified chiral soliton model by taking into account the effects of surrounding baryonic environment on the properties of in-medium baryons. The internal parameters of the model are determined based on nuclear phenomenology at nonstrange sector and fitted by reproducing nuclear matter properties near the saturation point. We get the equations of state in different nuclear environments such as symmetric nuclear matter, neutron and strange matter. The results for symmetric nuclear and neutron matter are in good agreement with the phenomenology of nuclear matter. The present results can be further applied to the description of compact stars.
