Mirror dark matter and the new DAMA/LIBRA results: A simple explanation for a beautiful experiment

Abstract

Recently, the DAMA/LIBRA experiment has convincingly confirmed the DAMA/NaI annual modulation signal, experimentally demonstrating the existence of nonbaryonic dark matter in the halo of our galaxy. Meanwhile, in another part of town, other experiments such as CDMS and XENON10 have not detected any evidence for dark matter. One promising dark matter candidate which can reconcile the positive DAMA annual modulation signal with the null results from the other experiments is mirror dark matter. We reanalyze the mirror matter interpretation of the DAMA annual modulation signal utilizing (a) the new data from DAMA/LIBRA, including the measured energy dependence of the annual modulation signal, (b..
