Kinetic recoupling of dark matter
Benjamin V. Lehmann, Logan Morrison, Stefano Profumo +1
We study the possibility that dark matter re-enters kinetic equilibrium with a radiation bath after kinetic decoupling, a scenario we dub kinetic recoupling. This naturally occurs,…
Sterile Neutrinos from Dark Matter: A Nightmare?
Logan Morrison, Stefano Profumo, Bibhushan Shakya
We provide a comprehensive study of observable spectra from dark matter pair-annihilation or decay into sterile (right-handed) neutrinos. This occurs, for instance, in neutrino por…
Hazma Meets HERWIG4DM: Precision Gamma-Ray, Neutrino, and Positron Spectra for Light Dark Matter
Adam Coogan, Logan Morrison, Tilman Plehn +2
We present a new open-source package, Hazma 2, that computes accurate spectra relevant for indirect dark matter searches for photon, neutrino, and positron production from vector-m…
Simulation Based Inference for Efficient Theory Space Sampling: an Application to Supersymmetric Explanations of the Anomalous Muon (g-2)
Logan Morrison, Stefano Profumo, Nolan Smyth +1
For the purpose of minimizing the number of sample model evaluations, we propose and study algorithms that utilize (sequential) versions of likelihood-to-evidence ratio neural esti…
Precision Gamma-Ray Constraints for Sub-GeV Dark Matter Models
Adam Coogan, Logan Morrison, Stefano Profumo
The indirect detection of dark matter particles with mass below the GeV scale has recently received significant attention. Future space-borne gamma-ray telescopes, including All-Sk…
Sterile Neutrino Dark Matter from Generalized -Symmetric Early-Universe Cosmologies
Adam Duran, Logan Morrison, Stefano Profumo
We generalize gravitational particle production in a radiation-dominated -symmetric universe to non-standard, but also -symmetric early universe cosmologies. We calculate…
