Muon (g-2):  Present Status and Future Possibilities 

The muon (g-2) experiment at the BNL AGS reached a relative precision of 
0.5 parts per million on the muon anomalous magnetic moment. Thanks to recent data from 
electron-positron annihilation to hadrons, the standard-model prediction has reached 
the same level of precision.  When compared, the two differ by 
3.4 standard deviations. Since the muon anomaly is sensitive to 
a wide range of physics beyond the standard model, agreement or 
difference with the standard-model will be important in 
constraining interpretations of discoveries that will be 
made at the LHC. The experiment and theory will be reviewed, 
and possibilities for improving both the theory and experimental 
values will be discussed, along with the implications for LHC data. 

A recent review of theory and experiment can be found in hep-ph/0703049, published in
