Commissioning the DIRC Detector and Searching for Axion-like Particles at GlueX
This thesis centers around problems in the study of the strong nuclear force. The GlueX DIRC, a Cherenkov radiation-based detector, was proposed to upgrade the particle identification capability of the GlueX experiment, which aims to perform quantitative tests of Quantum Chromodynamics in the …

The First Laboratory Searches for Low-Mass Axion Dark Matter
… to another long-standing mystery in physics, the strong CP problem. The Standard Model predicts that CP symmetry should be violated by the strong force. However, precision measurements have shown that strong interactions conserve CP symmetry to better than one part in 10¹⁰. At present, the most …

Development of the Magnetic Shielding and Rotational Stability Apparatus for use in the ARIADNE Project
… is a particle that is postulated to solve the Strong-CP problem, but also could account for all of the Dark Matter currently being observed in the Universe. Our group is involved in developing an experiment with the goal of detecting the QCD Axion. The Axion Resonant InterAction DetectioN …

Particle Physics in the LHC Era
… address the two of the outstanding theoretical problems of the SM - the Strong CP Problem and the fine tuning of the Higgs mass. We study models that solve or ameliorate these problems, and their implications for collider physics and astrophysics.</p>

Holographic and Composite Models of the Axion
… axion is composite, it must be bound by a novel strong interaction. Some strongly-coupled models, mathematically intractable until now, are recently discovered to be calculable through a mapping onto 5-dimensional gravity. We propose a series of composite and extra dimensional axion models. A …

A Charcuterie Platter of QCD Matter
… heavy quarks with masses much larger than the strong interaction scale decouple from the rest of the hadronization cascade. I also present exciting heavy quark phenomenology at existing colliders and the upcoming Electron-Ion Collider. The second question investigates the field theory structure …
