The last few years have brought us two new low-energy, precision measurements of hadronic parity violation, with the results suggesting that parity violation can be realized through one-pion exchange. Yet five low-energy SP (or Danilov) amplitudes also exist, and the present body of experimental results do not permit their direct determination from experiment. Thus theory continues to play an important role, predicting relationships between current and planned experiments.

The analysis of the Danilov amplitudes in large Nc QCD explains some features of the experimental results, though seemingly not all, given the most recent results. Further QCD studies should prove useful, and direct computation of two-nucleon matrix elements for hadronic parity violation in lattice QCD may also be within reach.

The workshop will focus on the current status of the data and their theoretical interpretation. An important goal of the workshop is to create a community roadmap for future experimental and theoretical work that will not only determine the Danilov amplitudes but also extract from them a deeper understanding of the interplay of the strong and weak interactions at low energies, thus providing a perspective on new experimental directions as well.

A workshop registration fee may apply. This workshop is sponsored in part by N3AS.
