My research group works with collaborators from around the world conducting research in subatomic physics. Since each nucleon (a proton or neutron) is a composite system of quarks, nucleons have a spectrum of excited states, called nucleon resonances. Knowledge of the properties of these excited states helps decipher the puzzle of how the quarks that make up these particles interact. At Jefferson Lab in Newport News, Virginia, my group has joined with collaborators using the CLAS Spectrometer in Experimental Hall B at Jefferson Lab, shown in Figure 1 below. We conduct experiments aimed at providing information crucial to a better description of these nucleon resonances. In particular, my group leads experiments probing these excitations nucleon resonances) with the photoproduction of eta mesons from nucleons, using high energy (up to 3.5 GeV) photons. We also participate in other collaboration experiments. We also work with collaborators at Jefferson Lab on an additional experiment, PrimEx, aimed at testing our understanding of the Standard Model of particles and interactions. That work uses the Primakov effect to explore the so-called axial anomaly in QCD.
