Multi-component Dark Matter through a Radiative Higgs Portal
Anthony DiFranzo, Gopolang Mohlabeng
We study a multi-component dark matter model where interactions with the Standard Model are primarily via the Higgs boson. The model contains vector-like fermions charged under $SU…
A 3.55 keV Line from Exciting Dark Matter without a Hidden Sector
Asher Berlin, Anthony DiFranzo, Dan Hooper
Models in which dark matter particles can scatter into a slightly heavier state which promptly decays to the lighter state and a photon (known as eXciting Dark Matter, or XDM) have…
Hidden On-Shell Mediators for the Galactic Center Gamma-Ray Excess
Mohammad Abdullah, Anthony DiFranzo, Arvind Rajaraman +3
We present simplified models for the galactic center gamma-ray excess where Dirac dark matter annihilates into pairs or triplets of on-shell bosonic mediators to the Standard Model…
