Abstract: After reviewing the basics of our current understanding of fundamental particles and their interactions, as enshrined in the Standard Model, Raymond Volkas briefly surveys the well-established evidence that this is an incomplete theory. The main part of the talk is then about recent measurements of the muon anomalous magnetic moment, and the rates of some B-meson decays, which point to possible further inadequacies of the Standard Model. Interestingly, the strongest current hints for this all involve muons.

Abstract: The nature and origin of dark matter is one of the key unresolved questions of fundamental physics. Astrophysical and cosmological data provide powerful probes of dark matter properties, although to date no signal has been confirmed. In this webinar Tracy Slatyer discusses a number of claimed possible signals of novel dark matter physics in astrophysical datasets, alternative explanations, and open questions, with a focus on the Galactic Center Excess in GeV-scale gamma rays.
