Muon g-2 experiment at Brookhaven National Laboratory

Abstract

By the end of an excellent data taking in 1999, we collected approximate to1 billion decay positrons with energy greater than 2 GeV and 30 mus after injection. The analysis of the 1999 data set were performed in parallel by various teams in the collaboration and each team provides a different approach to the analysis. The projected errors are expected to be of order 1.3 ppm statistical and below 0.5 ppm systematic. The data obtained in the 2000 run contains,approximate to4 times more decay positrons compared to 1999.
