TL;DR
This paper investigates whether the DAMA annual modulation signal can be explained by asymmetric mirror dark matter interacting through kinetic photon mixing, considering various astrophysical and particle physics uncertainties.
Contribution
It provides a model-independent analysis of the DAMA effect within asymmetric mirror dark matter, identifying relevant kinetic mixing parameter ranges under different astrophysical assumptions.
Findings
Kinetic mixing parameter ranges compatible with DAMA signal
Impact of halo model uncertainties on dark matter interactions
Constraints on mirror matter properties from experimental data
Abstract
The long-standing model-independent annual modulation effect measured by DAMA Collaboration is examined in the context of asymmetric mirror dark matter, assuming that dark atoms interact with target nuclei in the detector via kinetic mixing between mirror and ordinary photons, both being massless. The relevant ranges for the kinetic mixing parameter are obtained taking into account various existing uncertainties in nuclear and particle physics quantities as well as characteristic density and velocity distributions of dark matter in different halo models.
