A Possible Higher Precision-Measurement of the Muon G-2 Value

The theoretical motivation for and a possible experimental approach to higher precision measurement of the muon g−2 value are discussed. The goal is to measure a=(g−2)/2 to a precision of 0.3 ppm, which would be an improvement by a factor of 20 over the present value from a CERN experiment. The approach would involve a superconducting muon storage ring and would utilize the very high primary proton beam intensity now available at the Brookhaven National Laboratory AGS.
