Probing the nature of Dark Matter with the Large Scale Structure of the Universe
Emanuele Castorina, Universita degli Studi di Milano
Event Type: Informal Astro Talk
Time: 11:00 AM - 12:00 PM
Location: 726 Broadway, 940, CCPP Seminar
Abstract: In the standard cosmological model, the main non-baryonic component is defined by its acronym: Cold Dark Matter (CDM). In this talk I will show how measurements of the clustering of galaxies on scales larger than roughly 10 Mpc can place leading constraints on the physical properties behind each one of the acronym's letters, provided non-linearities in the matter distribution due to new physics are properly modeled via effective theories. Worked out examples will include ultra-light axions, strong kinetic coupling at late times, and tests of the equivalence principle in the dark sector.

Time: 12:30 PM - 1:30 PM

Three loop O(alpha alpha_s) corrections to the Top mass
Ciaran Williams, University at Buffalo
Event Type: HEP Seminar
Time: 2:00 PM - 3:15 PM
Location: 726 Broadway, 940, CCPP Seminar
Abstract: I will present the calculation of the mixed NLO EW - NNLO QCD corrections to the top quark mass. I will focus on solving the required Master Integrals at 3 loops and discuss how multi-loop Feynman integrals can be solved as iterated integrals of meromorphic differential forms. I will provide an introduction to the types of differential forms which appear in iterated integrals including an overview of elliptic functions needed to evaluate these integrals.
