Department of Physics & Astronomy Presents:
“PREX & CREX: Making neutron star measurements at home”

Abstract:
“The Pb radius and Ca radius experiments PREX and CREX will measure the neutron skins of lead and calcium, respectively, using parity-violating electron scattering. The asymmetry in polarized electron scattering provides access to the weak form factor, using a well-known charge form factor measured in unpolarized electron scattering experiments. The neutron skin of heavy nuclei is related to the neutron matter equation of state, so these measurements will have a direct impact on our understanding of neutron star structure. They will also have significant impact in other fields, such as heavy ion collisions and atomic parity violation. Furthermore, because ab initio calculations are possible on calcium it will serve as a bridge to the heavier nuclei in understanding nuclear structure, including the role of three nucleon forces. I will present the results for the first run of PREX, describe the experiment and summarize the status of the future measurements”
EVERYONE IS WELCOME!
