A Simple Dark Matter Model to Explain the LZ Event and Galactic Center Excess

Caleb Gemmell, Dan Hooper, Gordan Krnjaic

We propose that the dark matter (DM) is a pseudo-Dirac fermion with a mass of approximately GeV that couples inelastically to the Standard Model through a hadrophilic spin…

Getting Warmer: IceCube Nears Freeze Out

Mainak Mukhopadhyay, Gordan Krnjaic

IceCube has recently detected a diffuse population of high-energy neutrinos arising from the Milky Way. We use this high-significance detection to place new limits on dark matter (…

Baryogenesis via the CKM Matrix with Minimal Flavor Violation

Innes Bigaran, Gordan Krnjaic, Kevin Langhoff +1

It is often claimed Standard Model CP violation is insufficient for baryogenesis. We present a counterexample using minimal flavor violation (MFV) in which all CP-violating effects…

Probing the Cosmic Axion Background via Axion-Photon Conversion in Filaments

Duncan Rocha, Gordan Krnjaic, Matthew J. Baldwin

The cosmic axion background (CaB) is a hypothetical population of relativistic axions produced in the early universe. If the CaB is produced from dark matter decays, the axions in…

WIMP-like Dark Matter Without Thermalization At Freeze-Out

Dan Hooper, Gordan Krnjaic, Gabriele Montefalcone

In the standard thermal relic scenario, dark matter remains in chemical equilibrium with the Standard Model radiation bath until freeze-out occurs at , where i…

New Thermal-Relic Targets for sub-GeV Dark Matter Direct Detection

Xu Han, Gordan Krnjaic

Dark matter direct detection experiments involving electron recoils are beginning to test highly-predictive, thermal-relic milestones for sub-GeV dark matter models. Due to the Lee…
