Title: "Hedging One's Bets on Dark Matter"

Friday, February 7, 2020
3:00pm – 4:00pm
Wilder 104
Intended Audience(s): Public
Categories: Lectures & Seminars

Abstract:   I will briefly overview the arguments for two of the most compelling models for dark matter and describe the experimental challenges and strategies needed to make progress. I’ll discuss both direct and indirect searches for WIMP dark matter and Axions.  In particular, I will describe the promise of future gamma-ray measurements (CTA, APT) to either detect or essentially rule out well motivated WIMP models. 
I will go on to discuss how experiments like ADMX can search for QCD Axion dark matter, and describe the significant technical  challenges to cover the full natural parameter space.
In both cases I will try to emphasize what types of experiments are needed to constrain the most well-motivated, most generic models of dark matter.  I’ll also give my own opinion on where I believe it is worth a major investment of experimental effort but why one might be wise to hedge one’s bets!
