Query: Scalar Electroweak Multiplet Dark Matter   We revisit the theory and phenomenology of scalar electroweak multiplet
thermal dark matter. We derive the most general, renormalizable scalar
potential, assuming the presence of the Standard Model Higgs doublet, $H$, and
an electroweak multiplet $\Phi$ of arbitrary SU(2$)_L$ rank and hypercharge,
$Y$. We show that, in general, the $\Phi$-$H$ Higgs portal interactions depend
on three, rather than two independent couplings as has been previously
considered in the literature. For the phenomenologically viable case of $Y=0$
multiplets, we focus on the septuplet and quintuplet cases, and consider the
interplay of relic density and spin-independent direct detection cross section.
We show that both the relic density and direct detection cross sections depend
on a single linear combination of Higgs portal couplings, $\lambda_{\rm eff}$.
For $\lambda_{\rm eff}\sim \mathcal{O}(1)$, present direct detection exclusion
limits imply that the neutral component of a scalar electroweak multiplet would
comprise a subdominant fraction of the observed DM relic density.
