Mirror dark matter is a dissipative and self-interacting multiparticle dark matter candidate which can explain the DAMA, CoGeNT and CRESST-II direct detection experiments. This explanation requires photon-mirror photon kinetic mixing of strength epsilon similar to 10(-9). Mirror dark matter with such kinetic mixing can potentially leave distinctive signatures on the CMB anisotropy spectrum. We show that the most important effect of kinetic mixing on the CMB anisotropies is the suppression of the height of the third and higher odd peaks. If epsilon greater than or similar to 10(-9) then this feature can be observed by the PLANCK mission in the near future. (c) 2012 Elsevier B.V. All rights reserved.
