Upcoming HET and HEE Seminars



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)
- David Rittenhouse Laboratory, 3C4

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…



Experimental Particle Physics: Searching for Exotic and Rare Physics Processes with Liquid Argon Time Projection Chamber Detectors

Daisy Kalra (Columbia University)
- David Rittenhouse Laboratory, 3W2

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…

Past HET and HEE Seminars



High Energy Theory Seminar: Two dimensional QCD as a string theory

Ofer Aharony (Weizmann Institute of Science)
- David Rittenhouse Laboratory, 3W2

50 years after the duality of large N gauge theories to string theories was suggested, we still do not have a constructive method to find the string dual of a given gauge theory. I will review work in progress (in…



Experimental Particle Physics Seminar: Exotic Higgs decays & AI triggers at the LHC

Tae Min Hong (CERN)
- David Rittenhouse Laboratory, 3W2

Data at the LHC allows us to probe whether the Higgs boson communicates with unknown and/or undiscovered sectors beyond the Standard Model. I will discuss ATLAS results on the searches for Higgs decays to dark matter…



High Energy Theory Seminar: Making massive spin-2 particles from gravity during and after inflation

Andrew Long (Rice University)
- David Rittenhouse Laboratory, 3W2

The phenomenon of cosmological gravitational particle production (CGPP) occurs during and after inflation as quantum fields “feel” the cosmological expansion are excited out of their ground state.  CGPP is a…



High Energy Theory Seminar: Black Holes as the 21st century laboratory: New Tools and Prospects

Alfredo Guevara González (Harvard)
- David Rittenhouse Laboratory, 4N12

Recent breakthrough observations of black holes call for a new conceptual framework that unifies their analysis, from gravitational wave production to VLBI imaging of the photon ring. I will show how this is achieved…



High Energy Theory Seminar: Cornering axion(s) with direct detection and stellar probes

Edoardo Vitagliano (Hebrew U.)
- David Rittenhouse Laboratory, 3W2

Feebly interacting particles (FIPs), such as axions, scalars, dark photons, and majorons, are often theoretically well motivated, and a dark sector including one or more of them can both have the…
