Symmetries Beyond the Standard Model: Cosmology and Non-Accelerator Signatures
August 3, 2022 3:00 pm – 4:00 pm (CDT) MIST M102
Symmetries Beyond the Standard Model: Cosmology and Non-Accelerator Signatures

Speaker: Urjit A. Yajnik (Indian Institute of Technology, Bombay)Host: Doojin Kim

Neutrino physics presents a fascinating set of new phenomena yet hides some crucial evidence needed to relate these to other possibilities such as leptogenesis and lepton number violation. One generic feature of embedding the right chiral neutrino states in a gauge theory is the inevitable occurrence of Domain Walls in [...]
Searching for New Physics Using End-to-End Physics Reconstruction
September 14, 2022 4:00 pm – 5:00 pm (CDT)
Searching for New Physics Using End-to-End Physics Reconstruction

Speaker: Michael Andrews (Carnegie Mellon University)Host: Doojin Kim

Growing interest in searches for exotic new physics at CMS has highlighted the need for a new generation of particle reconstruction algorithms. For many exotic physics searches, sensitivity is constrained not by the ability to extract information from particle-level data but by inefficiencies in the reconstruction of the particle-level quantities [...]
Heavy Axions across Frontiers: Searches at Beam Dump Facilities and X-ray/Gamma-ray Telescopes
September 21, 2022 4:00 pm – 5:00 pm (CDT) MIST M102
Heavy Axions across Frontiers: Searches at Beam Dump Facilities and X-ray/Gamma-ray Telescopes

Speaker: Soubhik Kumar (Lawrence Berkeley National Laboratory)Host: Kevin Kelly

Heavy axions can arise in the context of Grand Unified theories where a confining dark gauge group unifies with the Standard Model (SM) gauge group. Depending on the strength of the axion coupling to the SM, heavy axion lifetimes can vary drastically, requiring very different observational probes. I will discuss [...]
A New Step in Interacting Dark Sector Cosmologies for the Hubble Tension and Large Scale Structure
September 28, 2022 4:00 pm – 5:00 pm (CDT) MIST M102
A New Step in Interacting Dark Sector Cosmologies for the Hubble Tension and Large Scale Structure

Speaker: Taewook Youn (University of Texas, Austin)Host: Doojin Kim

In this talk, I propose Stepped Partially Acoustic Dark Matter (SPartAcous), a new class of interacting dark sector models with a qualitatively new cosmological behavior that can simultaneously address the two most important tensions in cosmological data, the H0 and S8 tensions. The defining element of this class of models [...]

Boosting Light Dark Matter with Cosmic Rays and Supernovae
October 12, 2022 4:00 pm – 5:00 pm (CDT) MIST M102
Boosting Light Dark Matter with Cosmic Rays and Supernovae

Speaker: Christopher Cappiello (Queen's University)Host: Doojin Kim

Direct detection experiments set strong constraints on scattering between dark matter (DM) and nuclei, but rapidly lose sensitivity when the DM mass falls below ~10 GeV. Such light DM traveling at typical halo velocities doesn't carry enough momentum to trigger traditional detectors, so new techniques or low-threshold detectors are needed [...]
