Upper limit on dark matter mass in the inert doublet model

TL;DR

This paper determines the maximum possible dark matter mass in the inert doublet model, showing it can range from 20 to 80 TeV depending on the mass differences with other particles.

Contribution

It provides an analytic expression for the upper dark matter mass limit as a function of mass squared differences in the inert doublet model.

Findings

Upper limit varies between 20 and 80 TeV

Derived analytic expression for the upper bound

Dependence on mass squared differences

Abstract

We study the upper limit on dark matter mass in the context of the inert double model. We derive analytic expression for the upper bound as a function of the mass squared differences between dark matter and other new particles. We find that the upper limit varies between 20$-$80 TeV depending on the mass squared splitting.
