CPT and Lorentz Symmetry; The Standard-Model Extension

Dr Neil Russell does theoretical research focusing on testing the theory of relativity. The tool for this is the Standard-Model Extension, or SME, a framework that incorporates a variety of minuscule relativity 'violations.' The effects of these violations, if they exist, are measurable in sufficiently sensitive experiments. His recent research involves using the SME to figure out the signals that arise in various experimental systems. He has also worked on other theoretical topics, including quantum-mechanical supersymmetry and superalgebras.

Dr. Tireman and Collaborators Publish Results of Nucleon-Nucleon Experiment

Dr. Tireman had a paper titled “Probing the Repulsive Core of the Nucleon-Nucleon Interaction via the 4He(e,e'pN) Triple-Coincidence Reaction” published in Physical Review Letters by the American Physical Society. The paper explained results of an experiment conducted in collaboration with scientists at Jefferson National Laboratory and 47 other institutions to measure the nucleon-nucleon interaction at the repulsive core limit on helium-4.  The experiment was conducted in 2011 using the high-energy electron beam at Jefferson National Laboratory. Tireman’s involvement included constructing 18 plastic scintillation detectors with the help of NMU undergraduate students. He also assisted with experiment setup and data collection.
