WIDG Seminar: Samantha Pagan, Yale, “A Search for Solar Axions with CUORE”

Abstract: The Cryogenic Underground Observatory for Rare Events (CUORE) is an experiment searching for neutrinoless double-beta in Te-130. An observation of this ultra-rare decay would determine that neutrinos are Majorana particles. As an extremely low background experiment with high energy resolution and exposure, CUORE is sensitive to other rare-event searches such as for solar axions and Axion Like Particles (ALPs). Axions are a well-motivated dark matter candidate that could also provide a solution for the QCD Strong CP problem.

NPA Seminar: Shirley Li, UC Irvine/Fermilab, “Neutrino-Nucleus Scattering in Neutrino Oscillation Experiments”

: The Deep Underground Neutrino Experiment (DUNE) will be the leading next-generation particle project in the US. It aims to measure CP violation in the neutrino sector and determine the mass ordering of neutrinos. These measurements are straightforward conceptually but challenging practically. One outstanding issue is the modeling of GeV neutrino-nucleus interaction. With a lack of a proper theoretical framework, it is not only difficult to simulate neutrino events in the detector accurately but also difficult to assess its impact on the physics measurements.

NPA Seminar: Paolo Parotto, Penn State, “Finite density equation of state from lattice QCD: recent results from an alternative expansion”

Exploring the Quantum Chromodynamics (QCD) phase diagram has been the goal of extraordinary research efforts from theory and experiment alike. Knowledge of the QCD equation of state at finite temperature and density is crucial to support simulations of heavy-ion collisions. Although lattice simulations are the main tool of investigation for QCD thermodynamics, the determination of the equation of state of QCD at finite chemical potential from direct simulations is hindered by the fermion sign problem.
