Signatures of Dark Matter in Inert Triplet Models

TL;DR

This paper reviews dark matter signatures in two inert triplet models, highlighting the favored and excluded parameter spaces based on WMAP data and direct detection experiments.

Contribution

It compares the viability of two inert triplet models with different hypercharges in explaining dark matter observations.

Findings

Y=0 model favors dark matter around 5.5 TeV

Y=2 model is excluded by direct detection

Y=2 model allows dark matter around 2.8 TeV according to WMAP

Abstract

In this talk, we will review the signatures of dark matter in two inert triplet models. For the first model with the hypercharge Y=0, the dark matter mass around 5.5 TeV is favored by both the WMAP data and the direct detection. In contrast, for the second model of Y=2, it is excluded by the direct detection experiments although dark matter with its mass around 2.8 TeV is allowed by WMAP.
