Phase Structure of Strange Matter in a Non-topological Soliton Model

A non-topological soliton model with strange quarks is suggested to investigate the phase structure of strange matter. The results are qualitatively in agreement with that obtained by MIT bag model provided the ratio of coupling constants of different quarks to soliton scalar field x_σ ≡ g_gσ/g_qσ larger than a critical value x_c ~ 0.86, but as x_σ gets smaller than x_c, the phase structure may change.
