Muon anomalous magnetic moment: A harbinger for ''new physics''
Journal Article
·
· Physical Review D
Standard model loop contributions to the muon anomalous magnetic moment, a{sub {mu}}equivalent to(g{sub {mu}}-2)/2, and their theoretical uncertainties are scrutinized. The status and implications of the recently reported 2.6 sigma experiment versus theory deviation a{sub {mu}}{sup expt}-a{sub {mu}}{sup SM}=426(165) x 10{sup -11} are discussed. Possible explanations due to supersymmetric loop effects with m{sub SUSY}{approx_equal}55{sub -8}{sup +16}tan {beta} GeV, radiative mass mechanisms at the 1--2 TeV scale and other ''new physics'' scenarios are examined.
