We study the contributions to the anomalous magnetic moment of the muon from theories beyond the Standard Model, specifically supersymmetry. Results found at Brookhaven National Laboratory in 2001 during the E821 experiment indicate that current theories may not fully account for all of the interactions between the muon and fundamental gauge bosons. We re-derive Dirac's famous result of g=2. We then reproduce the one loop contributions from electroweak theory to the anomalous magnetic moment of the muon. We then use these calculations as a template for theories that go beyond the Standard Model. We show illustrative results for minimal supersymmetry in scenarios with Planck-scale supersymmetry breaking (MSUGRA), and determine parameter ranges that would be consistent with the anomalous magnetic moment discrepancy. In this way a sensitive probe like the anomalous magnetic moment of the muon may be used to constrain new physics.
