论文摘要
在这项工作中，我们研究了与通过相对论平均场（RMF）耐药模型获得的无量纲潮汐变形性$（λ）$相关的结果，包括短距离相关性（SRC）和暗物质（DM）含量[Phys [Phys。 Rev. D 105，023008（2022）]。作为黑暗粒子的候选者，我们使用Higgs玻色子交换与核子相互作用的最轻的中性诺物。特别是，我们测试了有关观察到来自Ligo and Pirgo Collaboration（LVC）的二进制中子星合并GW170817事件的引力波的限制的模型。我们表明$λ$随着暗粒子费米动量（$ k_f^{dm} $）的增加而减小。此功能有利于这里使用的RMF-SRC-DM模型，以满足$λ_{1.4} = 190^{+390} _ { - 120} $（$ 14M_ \ odot $ neutron star）和$ \tildeλ= 300 = 300^^by by+420} $}我们还表明，随着$ k_f^{dm} $的增加，$λ_1$和$λ_2$，即二进制系统的潮汐变形，也移至GW170817观测数据的方向。最后，我们验证系统中包含DM不会破坏\ mbox {$ i $ -love}关系（$λ$与惯性的无量纲时刻之间的相关性，$ \ bar {i} $）。 $ \ bar {i} _ \ star \ equiv \ bar {i}（m_ \ star）= 11.10^{+3.68} _ { - 2.28} $的观察数据，带有$ m_ \ star = 1.338m_ \ odot $。
In this work we study the outcomes related to dimensionless tidal deformability $(Λ)$ obtained through a relativistic mean-field (RMF) hadronic model including short-range correlations (SRC) and dark matter (DM) content [Phys. Rev. D 105, 023008 (2022)]. As a dark particle candidate, we use the lightest neutralino interacting with nucleons through the Higgs boson exchange. In particular, we test the model against the constraints regarding the observation of gravitational waves from the binary neutron star merger GW170817 event provided by LIGO and Virgo collaboration (LVC). We show that $Λ$ decreases as the dark particle Fermi momentum ($k_F^{DM}$) increases. This feature favors the RMF-SRC-DM model used here to satisfy the limits of $Λ_{1.4}=190^{+390}_{-120}$ ($Λ$ of a $1.4M_\odot$ neutron star), and $\tildeΛ=300^{+420}_{-230}$ given by the LVC. We also show that as $k_F^{DM}$ increases, $Λ_1$ and $Λ_2$, namely, tidal deformabilities of the binary system, are also moved to the direction of the GW170817 observational data. Finally, we verify that the inclusion of DM in the system does not destroy the \mbox{$I$-Love} relation (correlation between $Λ$ and dimensionless moment of inertia, $\bar{I}$). The observation data for $\bar{I}_\star\equiv\bar{I}(M_\star)=11.10^{+3.68}_{-2.28}$, with $M_\star=1.338M_\odot$, is attained by the RMF-SRC-DM model.
