Astrophysics Seminar: Near-field Cosmology with Stellar Streams
Nora Shipp (Carnegie Mellon)
Stellar streams, the tidal remnants of globular clusters and dwarf galaxies orbiting throughout the Milky Way’s halo, are some of the most powerful tools in the study of near-field cosmology. In particular, they are…
High Energy Theory Seminar: 5D SCFTs, Brane Webs, GTPs, Quivers and Geometry
Sebastian Franco (CUNY)
String/M-Theory provides various approaches for constructing 5d Superconformal Field Theories, most notably geometric engineering via M-theory on toric Calabi-Yau 3-folds and webs of (p,q) 5-branes in Type IIB String…
Condensed and Living Matter Seminar: Learning the shape of the immune and protein universe
Armita Nourmohammad (University of Washington)
The adaptive immune system consists of highly diverse B- and T-cell receptors, which can recognize a multitude of diverse pathogens. Immune recognition relies on molecular interactions between…
High Energy Theory Seminar: Topological defects on the worldsheet
Konstantinous Roumpedakis (Johns Hopkins University)
In this talk, I will discuss the implications of non-invertible topological defects on the worldsheet. I will consider two different setups where such defects arise in string theory. The first setup is toroidal…
Condensed and Living Matter Seminar: Randomness, Complexity, and the Biological Frontier
Pankaj Mehta (University of Boston)
The towering successes of twentieth century theoretical physics were marked by two guiding principles: symmetry and energy functionals (reflecting equilibrium dynamics). Yet how we…
Experimental Particle Physics: Searching for Exotic and Rare Physics Processes with Liquid Argon Time Projection Chamber Detectors
Daisy Kalra (Columbia University)
Neutrinos are some of the most abundant but elusive particles in the universe. The groundbreaking discovery of neutrino oscillations, recognized by the 2015 Nobel Prize, revealed the existence of non-zero neutrino…
High Energy Theory Seminar: Search for exotic Higgs boson decays with CMS and fast machine learning solutions for the LHC
Ho Fung Tsoi (University of Wisconsin-Madison)
There is still room for BSM physics in the scalar sector, which could manifest as Higgs boson decays to a pair of light pseudoscalars. I will present a search for such decay in final states with two b quarks and two…
Primakoff Lecture: Deciphering the Higgs boson: insights and revelations a decade after the discovery
Andreas Hoecker (CERN)
The discovery of the Higgs boson by the ATLAS and CMS experiments at CERN’s Large Hadron Collider (LHC) marks a breakthrough in particle physics, and it stands with the greatest scientific discoveries of all time.…
