Abstract:
The 2004 Brookhaven measurement of the muon's anomalous magnetic anomaly
was more than 3 standard deviations greater than the recently updated
Standard Model theory. Is this a sign of new physics? To answer this,
we built an even more sensitive experiment at Fermilab and have
completed four data-taking campaigns. I will describe this unique
experiment and its challenging data analysis. We published our first
results from the Run-1 analysis and learned that the BNL measurement was
not a fluke. Now what does it all mean and is the Standard Model
prediction stable? I will try to convince you that our experimental
results are to be trusted, but I will be speculating a bit on the new
physics implications and the status of the Standard Model prediction.
The talk will be aimed at a general audience.
