Trace-anomaly decomposition and universal dark matter scaling in compact stars
Adamu Issifu, Constança Providência, Tobias Frederico
We investigate how dark matter (DM) admixture modifies the conformal properties and phase structure of dense neutron-star matter within a self-consistent single-fluid framework, wi…
Effective field theory of scalar glueballs: Form factors and interaction radii
Adamu Issifu, Orlando Oliveira, Tobias Frederico
We develop a gauge-invariant effective field theory for scalar glueball interactions based on the Yang-Mills gluon condensate. Starting from a coherent-state formulation of the Yan…
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 dark matter admix neutron star framework based on a contact vector current--current interaction that couples the chemical potentials of both sectors th…
A self-consistent Higgs-portal framework for dark matter--admixed neutron stars: Collider-motivated benchmarks meet multimessenger constraints
Adamu Issifu
We investigate dark matter (DM)-admixed neutron stars (NSs) within a self-consistent single-fluid relativistic mean-field framework by extending the Higgs-portal model with a massi…
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…
