Abstract
We propose to continue our theoretical investigations of fundamental symmetries, and their
violations, with the end of connecting to experimental and observational probes of new
physics. We consider e?ects that could help to explain the cosmos’ gross excess of matter
over antimatter, and possibly the origin of its dark matter, as well as to illuminate whether
Majorana dynamics exists in Nature. In this project, a particular focus is on the interplay of
strong and weakly-coupled dynamics in low-energy processes with hadrons and nuclei within
and beyond the Standard Model. We propose to continue to study new mechanisms of CP
violation and of baryon number nonconservation, considering not only the prospects for the
discovery of baryon-number-violating processes at high-intensity, low-energy electron scat-
tering facilities, but also the new constraints that are possible from observational studies of
neutron stars and neutron star binaries. We also propose to continue to study the possibility
of CP violation in η decays, particularly in the process η → π+π0π−, for which extensive
experimental study is planned in the U.S. and worldwide. We also propose to study the
impact of the light quark mass di?erence on the theoretical description of radiative correc-
tions in neutron β decay in a systematic way, as this is necessary for the interpretation of
the next generation of ultra-precise experiments. Additionally, we propose to continue our
QCD analysis of hadronic parity nonconservation in few nucleon and nuclear systems, which
is important to the interpretation of experiments at the SNS. Finally, we plan to continue
our investigation of the manner in which magneto-optical e?ects can probe the structure of
matter and the possibility of new particles and forces.
