"The hadronic weak interaction - What we know and what we will learn''

Nucleons participate in the weak interaction; a neutron can beta decay into a proton, an electron and a neutrino. In addition, hadrons can scatter through the weak interaction without producing leptons. The signature of the hadronic weak interaction (HWI) is small violations of mirror symmetry. I will review the status of our knowledge of the HWI: theoretical framework, experimental results, and conclusions. I will discuss experiments underway and planned at the Spallation Neutron Source that will considerably improve our understanding of the HWI.

Refreshments will be served in CP 179 at 3:15 PM
