[Prex] [EXTERNAL] Abstract for DIS2022

[Weibin Zhang]

Dear collaborators:

Thank you for your helpful comments (special thanks to Chandan). Here is
the updated version, please check and comment on it, thank you.

The sister experiments PREX-II and CREX measured the parity-violating
scattering asymmetry of longitudinally polarized electrons off neutron-rich
targets: Pb208 and Ca48, from which we can extract the corresponding
neutron skin thickness and the density dependence of symmetry energy. The
excellent beam qualities and dedicated instrumentations at Jefferson Lab
allowed the measurements to be statistics limited. The high-precision
results from the above measurements helped to constrain the model
parameters that describe the compactness of neutron-rich matter. This talk
will report the used experimental techniques, the extracted final results
and their physical implications.

Best wishes,
Weibin
