Light thermal relics enabled by a second Higgs
Johannes Herms, Sudip Jana, Vishnu P. K. +1
Sub-GeV thermal relic dark matter typically requires the existence of a light mediator particle. We introduce the light two-Higgs-doublet portal, illustrated by a minimal UV-comple…
Minimal realization of light thermal Dark Matter
Johannes Herms, Sudip Jana, Vishnu P. K. +1
We propose a minimal UV-complete model for kinematically forbidden Dark Matter (DM) leading to a sub-GeV thermal relic. Our crucial realization is that the two-Higgs-doublet model…
Reevaluation of the cosmic antideuteron flux from cosmic-ray interactions and from exotic sources
Laura Šerkšnytė, Stephan Königstorfer, Philip von Doetinchem +8
Cosmic-ray antideuterons could be a key for the discovery of exotic phenomena in our Galaxy, such as dark-matter annihilations or primordial black hole evaporation. Unfortunately t…
