Precise Theory Predictions for Annihilation of Heavy WIMPs: Effective Field Theory and Bound State Effects
Abstract: I will discuss the status of weakly-interacting minimal dark matter scenarios, the importance of indirect searches in this context, and some general theoretical challenges in accurately computing annihilation signals for Weakly Interacting Massive Particles (WIMPs) with masses above the TeV scale. I will present new preliminary results for the case of SU(2) quintuplet dark matter, which can constitute all the dark matter with a standard cosmological history if its mass is around 14 TeV, incorporating both effective field theory methods to resum large logarithms and a detailed analysis of the bound state spectrum to account for contributions from bound state formation and decay.

Lumped Element Axion Detection at All Frequencies
Abstract: Lumped element detectors utilizing inductive couplings to an axion effective current represent a promising detection concept for light (neV-ueV) axion dark matter. Lumped element detectors that have been realized thus far have operated in a geometrically small limit that admits a magnetoquasistatic approximation for sensitivity calculations, but their sensitivities at higher frequencies have remained poorly understood. In this talk, I will present new work studying the sensitivity of lumped element detectors in the high-frequency limit, revealing new challenges and opportunities for the rapidly developing experimental paradigm.
