Reconciling the positive DAMA annual modulation signal with the negative results of the CDMS II experiment

Abstract

We examine the recent CDMS II results in the context of the mirror matter interpretation of the DAMA/NaI experiment.We find that the favoured mirror matter interpretation of the DAMA/NaI experiment -- a $H{e}^{\prime }/H^{\prime }$ dominated halo with a small $O^{\prime }$ component is fully consistent with the null results reported by CDMS II. While the CDMS II experiment is quite sensitive to a heavy $F{e}^{\prime }$ component, and may yet find a positive result, a more decisive test of mirror matter-type dark matter would require a lower threshold experiment using light target elements.
