Title: Neutral Weak Form Factor Measurements from the PREX-II and CREX Experiments

Abstract: The PREX-II and CREX experiments are two parity-violating electron experiments that were run at the Jefferson Lab CEBAF facility in 2019 and 2020. These experiments measure the parity-violating electroweak asymmetry in the elastic scattering of longitudinally spin-polarized electrons. These measurements seek to constrain the neutron radii in the nuclei of 208Pb in PREX-II and 48Ca in CREX. The PREX-II measurement has significant implications for the theory of uniform nuclear matter (such as that in neutron stars). The CREX measurement will provide useful information for nuclear theory helping bridge the gap between the current upper mass range of ab initio calculations and density functional theories more commonly used for heavy nuclei. My talk will feature a general overview of the work done in planning and running these two experiments, the particular challenges each experiment faced and how the analysis was done.
