Hadronic Parity Violation in Effective Field Theory

NSCL Seminar Room

The weak interaction between quarks induces a parity-violating component in the nucleon-nucleon interaction. Due to the nonperturbative nature of QCD at low energies, a detailed understanding of how the weak quark-quark interactions manifest themselves in the forces between nucleons remains elusive. Experiments in two-, three-, and few-nucleon systems (including photons) are being performed to map out this weak component of the nuclear force. A theoretical program to analyze and interpret the obtained data based on effective field theory will be presented. This approach provides a systematic and model-independent description of two- and few-nucleon observables. Results for parity-violating observables in the two- and three-nucleon sectors will be presented, including a discussion of the relevance of parity-violating three-nucleon interactions.
