The Leptonic Higgs and Dark Matter

TL;DR

This paper reviews a framework linking leptonic Higgs models to dark matter signals, explaining cosmic-ray anomalies and predicting detectable LHC signatures with light leptonic Higgs states.

Contribution

It summarizes a model that connects dark matter indirect signals with LHC leptonic Higgs sector phenomenology, highlighting new potential collider and astrophysical signatures.

Findings

Leptonic Higgs states are lighter than 200 GeV, producing large tau event rates at LHC.

Cosmic photon and neutrino signals from dark matter annihilation are constrained.

The framework explains recent cosmic-ray anomalies through leptonic Higgs interactions.

Abstract

This is a short review of the framework proposed in \cite{Goh:2009wg} which gives rise to indirect Dark Matter (DM) signals explaining the recent cosmic-ray anomalies and links cosmic-ray signals of DM to LHC signals of a leptonic Higgs sector.The states of the leptonic Higgs doublet are lighter than about 200 GeV, yielding large 2 tau and 4 tau event rates at the LHC. For the case of annihilations, cosmic photon and neutrino signals are constrained.
