Singly-heavy baryon in baryonic matter

초록

We investigate how the masses of singly heavy baryons undergo changes in nuclear matter, employing the framework of the in-medium modified chiral soliton model. The internal parameters are determined based on nuclear phenomenology at non-strange light baryonic matter and fitted by reproducing nuclear matter properties near the saturation density. We discuss the dependence of the in-medium masses of singly heavy baryons on strangeness and the portion of the neutrons in surrounding matter.
