Abstract: High precision parity-violating electron scattering (PVES) experiments have been used to study a wide range of physics. Besides tests of the standard model a series of nuclear studies have shown the versatility of PVES. Polarized elastic electron-nucleus scattering is sensitive to the neutral weak form factor and therefore provides measurements of the neutron distribution in a nucleus. Neutron rich nuclei are of particular interest because of their sensitivity to important parameters in the nuclear equation of state. The PREX2 experiment has recently completed its new data taking in 2019 using a longitudinally polarized electron beam at the CEBAF accelerator impinging on a 208Pb target. In this talk, I will discuss the overview of the experiment, the result as well as its implications.
