This grant supports a broad range of research in subatomic theory. Work in four particular directions will receive NSF support, two each by the PI and co-PI. However, these two researchers have interests in each other's work, so collaboration between the two is possible in any of these topics.Lebed and a collaborator will analyze the excited states of baryons (such as protons and neutrons) using a new formalism that has been developed for studying these short-lived states. He will also work to uncover the nature of patterns among the measured parameters from the masses and mixing of neutrinos, particles that emerge from both nuclear reactors and the sun.Belitsky will continue developing an approach to discern the most detailed possible information about the interior structure of protons, neutrons, and other strongly-interacting particles. He will also pursue his studies of a hidden symmetry that helps to shed light on the fundamental nature of quantum field theories with strong interactions.This grant will provide not only support to the PI and co-PI, but a postdoctoral research associate as well. Such a group of critical mass should be much more effective not only in producing published results, but also for disseminating our research findings as broadly as possible.
