| 英文摘要 | The two-equation-of-state model is used to describe the hadron-quark phase transition in asymmetric matter formed at high density in heavy-ion collisions. for the quark phase, the three-flavor nambu-jona-lasinio effective theory is used to investigate the influence of dynamical quark mass effects on the phase transition. at variance to the mit-bag results, with fixed-current quark masses, the main important effect of the chiral dynamics is the appearance of an end point for the coexistence zone. we show that a first-order hadron-quark phase transition may take place in the region t subset of (50-80) mev and rho(b) subset of (2-4)rho(0), which is possible to be probed in the new planned facilities, such as fair at gsi-darmstadt and nica at jinr-dubna. from the isospin properties of the mixed phase, some possible signals are suggested. the importance of chiral symmetry and dynamical quark mass on the hadron-quark phase transition is stressed. the difficulty of an exact location of a critical end point comes from its appearance in a region of competition between chiral symmetry breaking and confinement, where our knowledge of effective qcd theories is still rather uncertain. |
