A Program of Fundamental Symmetry Tests with Neutrons at the University of Kentucky

This grant supports the University of Kentucky’s contributions to fundamental symmetries experiments with neutrons. Searches for the neutron electric dipole moment (EDM) probe beyond-Standard Model sources of CP-violating physics. Our group has leading roles in two neutron EDM experiments under development – the world-leading-sensitivity Spallation Neutron Source experiment, and the intermediate-step-sensitivity experiment at Los Alamos National Laboratory. Precision measurements of neutron beta-decay angular correlations and the neutron lifetime probe the limits of the V−A symmetries underlying the Standard Model. Finally, precision measurements of hadronic parity- and time-violation in neutron reactions with various targets probe the weak quark-quark interaction.
