摘要:

在没有化学平衡假设的一般情况下,我们研究了从强子到夸克物质的相变。在手性平均场(CMF)模型的背景下,结合手征对称性恢复和解除禁闭,研究了净奇异性对电荷和同位旋分数、化学势和温度的影响.在何种程度上,这些量的探测过程中解除限制的条件下,预计存在于质子中子星,二进制中子星合并,和重离子碰撞进行了分析,通过建设的3维相图。

英文摘要:

We investigate the phase transition from hadron to quark matter in the general case without the assumption of chemical equilibrium. The effects of net strangeness on charge and isospin fractions, chemical potentials, and temperature are studied in the context of the Chiral Mean Field (CMF) model that incorporates chiral symmetry restoration and deconfinement. The extent to which these quantities are probed during deconfinement in conditions expected to exist in protoneutron stars, binary neutron-star mergers, and heavy-ion collisions is analyzed via the construction of 3-dimensional phase diagrams.
