The One-Loop Correction to Heavy Dark Matter Annihilation
Grigory Ovanesyan, Nicholas L. Rodd, Tracy R. Slatyer +1
We calculate the one-loop corrections to TeV scale dark matter annihilation in a model where the dark matter is described by an SU(2) triplet of Majorana fermions, such as the…
General Constraints on Dark Matter Decay from the Cosmic Microwave Background
Tracy R. Slatyer, Chih-Liang Wu
Precise measurements of the temperature and polarization anisotropies of the cosmic microwave background can be used to constrain the annihilation and decay of dark matter. In this…
Capture and Decay of Electroweak WIMPonium
Pouya Asadi, Matthew Baumgart, Patrick J. Fitzpatrick +2
The spectrum of Weakly-Interacting-Massive-Particle (WIMP) dark matter generically possesses bound states when the WIMP mass becomes sufficiently large relative to the mass of the…
Impeded Dark Matter
Joachim Kopp, Jia Liu, Tracy R. Slatyer +2
We consider dark matter models in which the mass splitting between the dark matter particles and their annihilation products is tiny. Compared to the previously proposed Forbidden…
Spherical Cows in Dark Matter Indirect Detection
Nicolás Bernal, Lina Necib, Tracy R. Slatyer
Dark matter (DM) halos have long been known to be triaxial, but in studies of possible annihilation and decay signals they are often treated as approximately spherical. In this wor…
The Darkest Hour Before Dawn: Contributions to Cosmic Reionization from Dark Matter Annihilation and Decay
Hongwan Liu, Tracy R. Slatyer, Jesús Zavala
Dark matter annihilation or decay could have a significant impact on the ionisation and thermal history of the universe. In this paper, we study the potential contribution of dark…
