Future Prospects for a Muon g-2 Experiment

The final results from the muon g-2 experiment at Brookhaven National Laboratory were published in 2004.~ The difference between the final experimental result and the current theoretical prediction for a$_{\mu }$ reveals a 3.4$\sigma $ discrepancy with the Standard Model, hinting at the possibility of new particles entering via quantum fluctuations.~ The experiment ended in a statistical error dominated regime, thus enabling a future generation muon g-2 experiment to be pursued with a higher muon flux and relatively minor modifications to the basic technique.~ The motivation for a new experiment will be discussed along with a description of design improvements and siting considerations for a new effort at BNL, FNAL, or JPARC.
