| Research Abstract |
We study possible existence of novel phases in high-density matter with multi-strangeness quantum numbers.Such phases may be realized in neutron-stars and may be formed through high-energy heavy-ion collisions. As multi-strangeness system, we consider both deeply bound multi-antikaonic states with hyperon-mixing in finite nulcei and kaon-condensed phase in hyperon-mixed matter in neutron stars.
On the basis of the relativistic mean-field theory for baryon-baryon interactions, coupled with the nonlinear effective chiral model which describes kaon-baryon and kaon-kaon interactions, we investigate structures and characteristic properties of these two phases, and clarify relations between them in a unified way.
