论文摘要
研究了保守的重子，同种和陌生电荷对密集物质中相变的行为的影响。在三大风味的Polyakov $ -Nambu $ - $ JONA-LASINIO型号中描述了Baryonic Matter，并考虑了几个电荷分数$ Y_Q $。讨论了矢量相互作用的作用，这对于描述密集系统很重要。由于其在重合离子碰撞和核心折叠超新星物质中的重要性，因此特别关注了案例的案例$ y_q = 0.4 $。结果表明，在非对称物质中，实验室中可能形成了手性对称夸克物质。此外，包含矢量相互作用会加强较低密度下夸克物质的形成。
The effect of conserved baryon, isospin and strangeness charges on the behavior of phase transitions in dense matter is studied. Baryonic matter is described within the three-flavor Polyakov$-$Nambu$-$Jona-Lasinio model and several charge fractions $Y_Q$ are considered. The role of the vector interaction, which can be important to describe dense systems, is discussed. Special attention is given to the case with charge fraction $Y_Q=0.4$, due to its importance in heavy-ion collisions and core-collapse supernova matter. It is shown that the possible formation of chiral-symmetric quark matter in the laboratory will be favored in asymmetric matter. Besides, the inclusion of the vector interaction reinforces the formation of quark matter at lower densities.
