FP(Q2, ? -gt 0) Q2
Use ?PT to extrapolate in small Q2 domain and
current PV experiments to determine LECs

17
Comparing Qwe and QWp
?? -gt e??e
Kurylov, Su, MR-M
18
Comparing Qwe and QWp
  • Can be a diagnostic tool to determine whether or
    not
  • the early Universe was supersymmetric
  • there is supersymmetric dark matter

The weak charges can serve a similar diagnostic
purpose for other models for high energy
symmetries, such as left-right symmetry, grand
unified theories with extra U(1) groups, etc.
