I will discuss three completed PV experiments\, Qweak\, PREX-I I\, CREX\, and one upcoming experiment\, MOLLER. The PREX-II and CREX asym metries are used to extract the difference in the radial distribution of th e protons and neutrons in Pb-208 and Ca-48 nuclei respectively\, which is r elated to the “stiffness” of nuclear matter. This measurement of the equat ion of state of nuclear matter is not just important to understand nuclei\, but can be applied to the properties of neutron stars. Qweak and MOLLER a re tests of the Standard Model of particle physics\, using the nearly zero weak charge of the proton and electron to search for evidence of new physic s. Qweak measured an asymmetry consistent with the Standard Model predicti on\, pushing the lower mass limit on new semi-leptonic parity-violation phy sics to above 3.5 TeV. MOLLER’s measurement is expected to be sensitive to particles contributing to the electron-electron scattering of masses aroun d 7.5 TeV.
