A self-consistent Higgs-portal framework for dark matter--admixed neutron stars: Collider-motivated benchmarks meet multimessenger constraints
Adamu Issifu
The paper develops a self-consistent relativistic mean‑field model that couples baryonic matter and dark matter in neutron stars via a Higgs‑portal with a massive Z′ vector mediato…
A self-consistent single-fluid framework for neutron stars admixed with mirror dark matter
Adamu Issifu, Constança Providência, Franciele M. da Silva +2
We develop a self-consistent framework based on a contact vector current-current interaction that couples the chemical potentials of both sectors through mutual mean-field shifts,…
Rotational enhancement and stability of protoquark stars during thermal evolution
Adamu Issifu, Andreas Konstantinou, Prashant Thakur +1
We present the first systematic study of rigidly rotating protoquark stars based on isentropic equations of state (EOS) within the density-dependent quark mass (DDQM) framework. Us…
Rotational effects in quark stars: comparing different models
Adamu Issifu, Andreas Konstantinou, Franciele M. da Silva +1
We investigate the rotational properties of self-bound strange quark stars using two representative quark matter equations of state (EOS): the vector MIT bag model and the density-…
Dark Matter Heating in Evolving Proto-Neutron Stars: A Two-Fluid Approach
Adamu Issifu, Prashant Thakur, Davood Rafiei Karkevandi +4
Neutron stars (NSs) provide a unique laboratory to probe dark matter (DM) through its gravitational imprint on stellar evolution. We use a two-fluid framework with non-annihilating…
Tachyonic AdS/QCD, Determining the Strong Running Coupling and β-function in both UV and IR Regions of AdS Space
Adamu Issifu, Elijah A. Abbey, Francisco A. Brito
In this paper, we investigate the Quantum Chromodynamics (QCD)-like running coupling, , and its associated -function within a tachyonic Anti-de Sitter (AdS)/…
