Incorporating the weak mixing angle dependence to reconcile the neutron skin measurement on ²⁰⁸Pb by PREX-II

NUCLEAR REACTIONS ²⁰⁸Pb(polarized e^-, e^-), E=953 MeV; analyzed experimental results of PREX-II experiment reported by 2021Ad10 by fixing the weak mixing angle to its standard model, and using atomic parity violation (APV) experimental results on ²⁰⁸Pb in order to explain the disagreement between PREX-II result and the theoretical nuclear-model predictions, as well as several previous experimental measurements of neutron skin thickness of ²⁰⁸Pb; calculated asymmetry and σ values under the DWBA using modified DREPHA code; deduced neutron skin thickness. Relevance to upcoming P2, MOLLER, MREX, and CREX experiments for resolution of disagreements in results.

New insights into nuclear physics and weak mixing angle using electroweak probes

NUCLEAR REACTIONS ¹³³Cs, ¹²⁷I(ν, ν), E=2-100 MeV; analyzed coherent elastic neutrino-nucleus scattering data in cesium-iodide crystal from the COHERENT experiment, and from atomic parity violation (APV) experiment. ¹³³Cs, ¹²⁷I; deduced most precise neutron rms radii, and the neutron skin values, independent low-energy weak mixing angle with uncertainty and compared with standard model prediction. ¹²⁷I, ¹³³Cs, ²⁰⁸Pb; calculated rms proton and neutron point and physical radii and the neutron skins using nonrelativistic Skyrme-Hartree-Fock (SHF) and relativistic mean-field (RMF) nuclear models, point neutron skin predictions for ²⁰⁸Pb and ¹³³Cs according to different models and comparisons with data from PREX-I, PREX-II, and COHERENT+APV experiments.
