DOI: 10.1007/jhep08(2024)095
Abstract: We reappraise the viability of asymmetric dark matter (ADM) realized as a Dirac fermion coupling dominantly to the Standard Model fermions. Treating the interactions of such a DM particle with quarks/leptons in an effective-interactions framework,… read more here.

DOI: 10.1088/1475-7516/2025/08/013
Abstract: We implement the asymmetric dark matter framework, linking the ordinary and dark matter abundances, within a supersymmetric context. We consider a supersymmetric model that respects an approximate U(1) R symmetry, which is broken in such… read more here.

DOI: 10.1088/1674-1137/abc068
Abstract: We investigate the evolution of abundance of the asymmetric thermal Dark Matter when its annihilation rate at chemical decoupling is boosted by the Sommerfeld enhancement. Next, we discuss the effect of kinetic decoupling on the… read more here.

DOI: 10.1103/physrevd.97.103510
Abstract: Asymmetric dark matter (ADM) is motivated by the similar cosmological mass densities measured for ordinary and dark matter. We present a comprehensive theory for ADM that addresses the mass density similarity, going beyond the usual… read more here.

DOI: 10.1103/physrevd.99.083008
Abstract: We consider gravitationally bound states of asymmetric dark matter (ADM stars), and the impact of ADM capture on the stability of neutron stars. We derive and interpret the equation of state for ADM with both… read more here.
