    Panel discussion (Moderator Jorge Piekarewicz): PREX and Nuclear Physics and Astrophysics Correlations between the 208Pb neutron radius and:

    1. The weak charge form factor at the kinematics of PREX
    2. The central baryon density in 208Pb and the saturation density of nuclear matter
    3. The skin thickness of very neutron rich nuclei
    4. The neutron radius in other Atomic PNC nuclei
    5. The density dependence of the symmetry energy and the neutron matter EOS at subnuclear density
    6. The transition density between crust and core in neutron stars
    7. The threshold mass for direct URCA cooling of NS
    8. The extent of the pasta phases in neutron star crust
    9. The radius of neutron stars
