In this work we study a relativistic mean-field (RMF) hadronic model, with
nucleonic short-range correlations (SRC) included, coupled to dark matter (DM)
through the Higgs boson. We study different parametrizations of this model by
running the dark particle Fermi momentum, and its mass in the range of 50 GeV
⩽Mχ⩽500 GeV, compatible with experimental
spin-independent scattering cross-sections. By using this RMF-SRC-DM model, we
calculate some neutron star quantities, namely, mass-radius profiles,
dimensionless tidal deformabilities, and crustal properties. Our findings show
that is possible to construct RMF-SRC-DM parametrizations in agreement with
constraints provided by LIGO and Virgo collaboration (LVC) on the GW170817
event, and recent observational data from the NICER mission. Furthermore, we
show that the increase of Mχ favors the model to attain data from LVC
regarding the tidal deformabilities. Higher values of Mχ also induce a
reduction of the neutron star crust (mass and thickness), and cause a decrease
of the crustal fraction of the moment of inertia (Icrust/I).
Nevertheless, we show that some RMF-SRC-DM parametrizations still exhibit
Icrust/I>7%, a condition that explains the glitch activity in
rotation-powered pulsars such as the Vela one. Therefore, dark matter content
can also be used for describing such a phenomenon.Comment: 10 pages, 8 figures. Published in Monthly Notices of the Royal
