Particle Seminar: Maxim Pospelov (U of Minnesota), “Revisiting Standard-Model-induced EDMs”
Title: Revisiting Standard-Model-induced EDMs Abstract: I review the SM-induced EDMs, namely the contributions from the QCD theta term and the Kobayashi-Maskawa phase. I concentrate on the electron-spin-dependent EDMs, which saw more than two orders of magnitude progress in the last two decades. I will try to convince you that although quite small, the result is much larger than previously believed. I will finish … Read More
Particle Seminar: Asimina Arvanitaki (Perimeter), “Superradiant interactions of cosmic noise”
Title: Superradiant interactions of cosmic noise Abstract: In this talk, I will describe three things. First, I will outline the conditions under which the interaction rate of inelastic processes that change the internal state of a system of N targets scales N2. This is an effect distinct from coherent elastic scattering, but with the same scaling. These inelastic processes are a generalization … Read More
Particle Seminar: Hannah Banks (CERN) “Searching for Ultra-light dark matter with atomic & nuclear clocks and Interferometers”
Title: Searching for Ultra-light dark matter with atomic & nuclear clocks and Interferometers Abstract: Fundamental physics has come to somewhat of a crossroads. With the as-yet absence of new particles at high energy colliders it has become increasingly attractive to consider the possibility that the new physics we seek has remained hidden not by an inaccessible energy barrier but via incredibly weak … Read More
