Description

In the 40 years since the landmark E122 experiment, parity violating electron scattering (PVES) has proven to be a versatile and precise tool in both setting limits on beyond the standard model physics and in determining properties of nuclear matter. Its appeal stems from the use of the cleanly interpretable weak neutral current. Updated experimental techniques will allow a new generation of PVES experiments to better determine the weak charges of both the electron and proton, setting limits on possible new interactions not accounted by the standard model. Deep inelastic scattering off deuterium will provide new information on the nucleon partonic structure and test beyond the standard model physics processes to tens of TeV mass scale. In the immediate future this technique will be used to determine the neutron skin on heavy nuclei. This will constrain the nuclear equation of state in neutron rich media and provide a crucial comparison to recent results obtained from binary neutron star mergers. This talk will give an overview of recent PVES results and detail the future experiments listed above.
