Abstract: Mirror dark matter provides a simple framework for which to explain theDAMA-Libra annual modulation signal consistently with the null results of theother direct detection experiments. The simplest possibility involves ordinarymatter interacting with mirror dark matter via photon-mirror photon kineticmixing of strength epsilon ~ 10^-9. We confirm that photon-mirror photonmixing of this magnitude is consistent with constraints from ordinary Big Bangnucleosynthesis as well as the more stringent constraints from cosmic microwavebackground measurements and large scale structure considerations.
