Abstract:
SLAC experiment E158 has made a very precise measurement of parity
violation in electron-electron (Moller) scattering. The spin
asymmetry, measured with an uncertainty of about 18 parts per billion,
determines the weak mixing angle at low energies with unprecedented
precision. Combined with the measurements of at the
pole, our result establishes the running of the weak mixing angle
with over significance. I will discuss the experiment, the
final results, and their implications for the various new physics
models.
