Precision measurements and 'New Physics
Description
The role of precision measurements in testing the standard model and probing for 'New Physics' is described. Anomalous magnetic moments of the electron (ae) and muon (aμ) along with the radiative correction functions Δr and Δ r-hat that relate α, Gμ, mz, mw and sin2 θw(mz)ms are discussed. Current discrepancy between aμ theory and experiment is correlated with constraints on the Higgs mass from mw and sin2 θw(mz)ms obtained from Z pole lepton asymmetries. Together, they suggest hints of 'New Physics' may be starting to appear in quantum loop effects. (sakurai lecture)
