标题： Strongly Interacting Quark Matter in Massive Quark Stars

摘要： 本文研究了在高重子密度（$\rho_B$）下强耦合物质的性质，在中子星（QS）中进行。QS是通过密度依赖夸克质量模型（DDQM模型）构建的，修改后的（MDDQM模型）用于获得更高的最大引力质量（$\rm M_{max}$）的QS，使用观测脉冲星的数据：HESS J1731$-$347，PSR J0030$+$0451，PSR J0740$+$6620，以及PSR J0952$-$0607作为贝叶斯推断中的约束条件来确定模型参数。 产生夸克物质（QM）状态方程的参数导致$\rm M_{max} > 2M_\odot$违反了在高$\rho_B$下分析的近共形条件。 这种行为被解释为随着$\rho_B$的增加，夸克种群不断增长，同时形成带色的夸克和胶子凝聚态，这两者都受到星体核心压力增加的影响，当$\rho_B$上升时。 这在所采用的 MDDQM 模型中有所体现，该模型引入了一个在高密度下变得重要的附加项。 另一方面，产生$\rm M_{max} < 2M_\odot$的参数在较高密度下符合预期的近共形行为，如分析所示。 显示英文摘要

摘要： This paper investigates the properties of strongly coupled matter at high baryon densities ($\rho_B$) in a quark star (QS). The QS is built from the density-dependent quark mass model (DDQM model), modified (MDDQM model) to obtain a higher maximum gravitational mass ($\rm M_{max}$) of the QS, using the data from observed pulsars: HESS J1731$-$347, PSR J0030$+$0451, PSR J0740$+$6620, and PSR J0952$-$0607 as constraints in Bayesian inference to determine the model parameters. The parameters yielding a quark matter (QM) equation of state that generates $\rm M_{max} > 2M_\odot$ violate the near-conformality conditions analyzed at high $\rho_B$. This behavior is interpreted as a consequence of the increasing quark population with $\rho_B$, along with the simultaneous formation of colored quark and gluon condensates, both of which are influenced by the pressure build-up in the stellar core as $\rho_B$ rises. This is reflected in the MDDQM model employed, which introduces an additional term that becomes significant at high densities. On the other hand, parameters that yield $\rm M_{max} < 2M_\odot$ conform to the expected near-conformal behavior at higher densities, as analyzed.
