Tests of Fundamental Symmetries with Neutrons
Leah Broussard, Oak Ridge Laboratory,

By studying the neutron, we can gain insight into the fundamental laws describing the particles and interactions in nature.  The neutron's properties depend upon the presence of symmetries which form the basis for the Standard Model.  A nonvanishing electric dipole moment of the neutron could signal a new source of charge-conjugation and parity symmetry violation, which is currently too small to explain the lack of antimatter in the universe.  Further, the beta decay of the neutron is an excellent system to study the parity-violating nature of the weak interaction, and is sensitive to new physics beyond the Standard Model.  This presentation will introduce you to two high-sensitivity experiments which will test these symmetry violations and provide a unique probe of particle physics separate from high energy collider experiments.
