We investigate the constraints on the scalar, vector and spin-3/2 dark matter
interaction with the standard model particles, from the observations of dark
matter relic density, the direct detection experiments of CDMS and XENON, and
the indirect detection of the antiproton-to-proton ratio by PAMELA. A model
independent way is adopted by constructing the most general 4-particle
effective interaction operators up to dimension 6 between dark matter and
standard model particles. We find that the constraints from different
experiments are complementary with each other, and the comparision among these
constraints may exclude some effective models of dark matter and limit the
parameters of some others. The spin-independent direct detection gives very
strong constraints for some operators, while the indirect detection of
antiproton-to-proton data can be more sensitive than direct detection or relic
density for light dark matter (whose mass less than 70 GeV) in some cases. The
constraints on some operators for spin-3/2 dark matter are shown to be similar
to those on their analogous operators for Dirac fermionic dark matter. There
are still some operators not sensitive to the current dark matter direct and
indirect search experiments.
