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 $M_{max,T}$ 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, ${\mathrm{f}}_{DM}$, we put constraints in the parameter space ${\mathrm{f}}_{DM}-p_{\mathrm{DM}}^{\prime }∕p_{\mathrm{OM}}^{\prime }$. Our bounds are sensitive to the recently observed NSs total masses.

在本文中，我们研究了“ hyperon难题”，尽管这个问题仍然需要大量研究才能解决。该问题的解决方案需要一种或多种机制，这些机制最终可以提供使EoS变硬所需的额外排斥力，因此，${\mathrm{中号}}_{最高，Ť}$符合当前的观测极限。在本文中，我们提出将中子星（NSs）中的暗物质（DM）与普通物质混合在一起，可以改变静水力平衡，并且可以解释所观察到的差异，而与高子的多体相互作用无关，这似乎是不可避免的。

我们研究了非自消灭，自相互作用的DM与普通物质混合的NS如何改变其内部结构，并讨论了此类NS的质量半径关系。我们考虑了1、10和100 GeV的DM颗粒质量，同时考虑了DM相互作用强度的丰富列表，$ÿ$。

通过分析多维参数空间，包括多个量，例如：DM的相互作用强度； b。DM颗粒质量及其内部的DM量； c。DM分数，${\mathrm{F}}_{d\mathrm{中号}}$，我们将约束放在参数空间中 ${\mathrm{F}}_{d\mathrm{中号}}-p_{\mathrm{DM}}^{\prime }∕p_{\mathrm{OM}}^{\prime }$。我们的边界对最近观测到的NSs总质量敏感。
