Polarization effects due to dark matter interaction between massive standard particles

Abstract

We propose deeper tests of the existence of DM interactions between heavy particles in $e^{+}{e}^{-}\to t\bar{t},ZZ,W^{+}{W}^{-}$ by looking at the effects on final state polarization. We show that indeed $t$, $W$ and $Z$ polarization are particularly sensitive to the structure of these interactions, to their relation with the origin of the masses and to the quantum numbers of the possibly exchanged dark particles.
