论文摘要
In this paper, we studied the ``hyperon puzzle", a problem that nevertheless the large number of studies is still an open problem. The solution of this issue requires one or more mechanisms that could eventually provide the additional repulsion needed to make the EoS stiffer and, therefore, the value of $M_{\rm{max}, T}$ compatible with the current observational limits. In this paper we proposed that including dark matter (DM)在中子星(NSS)中与普通物质混合,改变了静水平衡,并且可以解释观察到的差异,而与超子多体相互作用无关,这似乎是不可避免的。 我们已经研究了非自我宣传和自我互动是如何与NSS中普通物质混合的如何改变其内部结构,并讨论了这种NSS的质量 - 拉迪乌斯关系。我们认为DM粒子质量为1、10和100 GEV,同时考虑到DM相互作用的丰富列表,即$ Y $。 通过分析多维参数空间,其中包括:a。 DM相互作用强度,b。 DM颗粒质量以及其内部DM的数量以及c。 DM分数,$ {\ rm f} _ {dm} $,我们将约束放在参数space $ {\ rm f} _ {dm} -p^{\ prime} _ {\ prime} _ {\ rm dm dm}/p^{\ rm dm}/p^{\ prime} {\ prime} _ {\ prime} _ {我们的边界对最近观察到的NSS总质量敏感。
In this paper, we studied the ``hyperon puzzle", a problem that nevertheless the large number of studies is still an open problem. The solution of this issue requires one or more mechanisms that could eventually provide the additional repulsion needed to make the EoS stiffer and, therefore, the value of $M_{\rm{max}, T}$ compatible with the current observational limits. In this paper we proposed that including dark matter (DM) admixed with ordinary matter in neutron stars (NSs), change the hydrostatic equilibrium and may explain the observed discrepancies, regardless to hyperon multi-body interactions, which seem to be unavoidable. We have studied how non-self-annihilating, and self-interacting, DM admixed with ordinary matter in NSs changes their inner structure, and discussed the mass-radius relations of such NSs. We considered DM particle masses of 1, 10, and 100 GeV, while taking into account a rich list of the DM interacting strengths, $y$. By analyzing the multidimensional parameter space, including several quantities like: a. the DM interacting strength, b. the DM particle mass as well as the quantity of DM in its interior, and c. the DM fraction, ${\rm f}_{DM}$, we put constraints in the parameter space ${\rm f}_{DM} - p^{\prime}_{\rm DM}/p^{\prime}_{\rm OM}$. Our bounds are sensitive to the recently observed NSs total masses.
