Anomalous Magnetic Moment of Muon and g-2 Experiment JAEHYUNG CHOI, SUNY at Stony Brook, NY — The magnetic moment of a particle is one of the physical quantities which can
be measured by the experiment and be testified by the theory. Especially, the magnetic moment of electron is precisely measured and is
very well-matched with the expected value by QED. Considering loop
corrections, it shows marvelous accuracy of QED and supports the validity of Standard Model. In the case of muon which is very similar to
electrons except for mass, we get quite precise magnetic moment but the
discrepancy between expected and measured values is larger than that
of electrons. This is called anomalous magnetic moment of muon which
is a topic of my talk. I will explain the theoretical aspects of anomalous
magnetic moment of muon and also briefly cover E821 experiment for
g-2 measurement.
