In http://de.arxiv.org/abs/astro-ph/0405282 the 7 year results of the DAMA/NaI dark matter direct detection experiment show a signal significant at 6.3σ according to the authors. An explanation for why a signal from mirror-baryonic matter should be expected in this experiment but not in others with similar cross-section detection parameters is presented in AstroPh:0403043, see also AstroPh:0407623 and references therein.
Aim: Check the experimental and theoretical claims and propose further tests
Try to find an alternative explanation for the DAMA/NaI results without going beyond the Standard Model of particle physics
Check whether the Foot et al. calculations of mirror matter properties are consistent with all the experimental data as the authors claim
Extend the Foot et al. calculations to find, e.g. a non-gravitational effect of mirror matter in stellar physics, e.g. symbiotic stars (gravitational effects of dark matter are already well studied)
