Description
The $^{48}$Ca nucleus provides an important testing ground for models (both density functional and ab-initio) trying to describe the arrangement of both protons and neutrons in nuclei. The parity violating electron scattering asymmetry from the unpolarized $^{48}$Ca nucleus gives direct access to its weak form factor. Using data collected with the CEBAF accelerator at Jefferson Lab in 2020 the CREX collaboration has completed a blinded analysis of this quantity. This talk will describe the experiment, data analysis and systematic control, as well as the implications of this result on our understanding of nuclear matter.
