Research

Professor Chupp and his group pursue a program that uses precision measurement techniques and symmetry principles in particle physics investigations and applies the technology developed for those investigations to a variety of endeavors. The primary current efforts include fundamental neutron physics and atomic and neutron electric-dipole-moment measurements. Neutron beta-decay provides a unique window into new physics, and we are contributing to a new generation of high precision experiments including the rare radiative decay mode of the neutron, the possibility of an improved cold-beam neutron lifetime measurement and Nab, measurement of the beta-neutrino asymmetry using a magnetic proton-time-of-flight spectrometer. Time reversal invariance violation is also manifest in the permanent electric dipole moments (EDMs) induced in the neutron and atoms by elementary particle interactions beyond the Standard Model that may hold the key to the origin of matter. Rare isotopes, e.g. 223-Rn, are used because large enhancements of time-reversal violating effects are expected due to octupole deformation of the nucleus. Experiment S-929 at TRIUMF will measure the EDM of 223-Rn. The Facility for Rare Isotope Beam, FRIB, at Michigan State University can produce much greater quantities of 223-Rn and provide for more precise measurements. Recent results on direct measurement of nuclear shapes at CERN-ISOLDE help guide this effort. We also work with Peter Fierlinger’s group at Technical University of Munich on a new neutron EDM measurement. Our group continues to work on applications of laser polarized 129-Xe to medical imaging.
