Description

The DAMA, CoGeNT and CRESST-II experiments have announced evidence for the direct detection of dark matter. We discuss these results in the context of the mirror dark matter framework. We show that all three experiments can be simultaneously explained via kinetic mixing induced elastic scattering of a mirror metal component off target nuclei. This metal component can be as heavy as Fe$'$ if the galactic rotational velocity is relatively low: $v_{rot} < 220$ km/s. This explanation is consistent with the constraints from the other experiments, such as CDMS/Ge, CDMS/Si and XENON100 when modest $\sim 20-30\%$ uncertainties in energy scale are considered.
