Loop Dominated Signals from Neutrino Portal Dark Matter
Hiren H. Patel, Stefano Profumo, Bibhushan Shakya
We study scenarios where loop processes give the dominant contributions to dark matter decay or annihilation despite the presence of tree level channels. We illustrate this possibi…
Superradiance and the Spins of Black Holes from LIGO and X-ray binaries
Nicolas Fernandez, Akshay Ghalsasi, Stefano Profumo
Measurements of the spin of stellar mass black holes (BHs) are now possible both through LIGO observations of binary BH mergers and for BHs in X-ray binary systems. The spins of BH…
One-Loop Charge-Breaking Minima in the Two-Higgs Doublet Model
Pedro M. Ferreira, Logan A. Morrison, Stefano Profumo
We analyze the vacuum structure of the one-loop effective potential in the two Higgs doublet model. We find that electroweak-breaking vacuua can coexist with charge breaking ones,…
An Introduction to Particle Dark Matter
Stefano Profumo, Leonardo Giani, Oliver F. Piattella
We review the features of Dark Matter as a particle, presenting some old and new instructive models, and looking for their physical implications in the early universe and in the pr…
On the origin of the gamma-ray emission from Omega Centauri: Milisecond pulsars and dark matter annihilation
Javier Reynoso-Cordova, Oleg Burgueño, Alex Geringer-Sameth +3
We explore two possible scenarios to explain the observed gamma-ray emission associated with the atypical globular cluster Omega-Centauri: emission from millisecond pulsars (MSP) a…
Hazma: A Python Toolkit for Studying Indirect Detection of Sub-GeV Dark Matter
Adam Coogan, Logan Morrison, Stefano Profumo
With several proposed MeV gamma-ray telescopes on the horizon, it is of paramount importance to perform accurate calculations of gamma-ray spectra expected from sub-GeV dark matter…
