Query: Probe of New Physics using Precision Measurement of the Electron
  Magnetic Moment   The anomalous magnetic moment of the electron is determined experimentally
with an accuracy of $2.8\times 10^{-13}$ and the uncertainty may decrease by an
order of magnitude in the future. While the current data is in excellent
agreement with the standard model, the possible future improvement in the error
in $\Delta a_e= a_e^{\text{exp}}- a_e^{\text{theory}}$ has recently drawn
interest in the electron anomalous magnetic moment as a possible probe of new
physics beyond the standard model. In this work we give an analysis of such
physics in an extension of the minimal supersymmetric standard model with a
vector multiplet. In the extended model the electroweak contribution to the
anomalous magnetic moment of the electron include loop diagrams involving in
addition to the exchange of W and Z, the exchange of charginos, sneutrinos and
mirror sneutrinos, and the exchange of neutralinos, sleptons and mirror
sleptons. The analysis shows that a contribution to the electron magnetic
moment much larger than expected by $m_e^2/m_\mu^2$ scaling of the deviation of
the muon anomalous magnetic moment over the standard model prediction, i.e.,
$\Delta a_\mu = 3 \times 10^{-9}$ as given by the Brookhaven experiment, can be
gotten within the MSSM extension. Effects of CP violating phases in the
extended MSSM model on the corrections to the supersymmetric electroweak
contributions to $a_e$ are also investigated. The analysis points to the
possibility of detection of new physics effects with modest improvement on the
error in $\Delta a_e= a_e^{\text{exp}} - a_e^{\text{theory}}$.
