Muon measurements bounce back

30 Jul 2002

New measurements of the magnetic moment of the muon are set to re-ignite the debate over the Standard Model, which has successfully explained the results of particle physics experiments for over 30 years. Twice as precise as the previous best measurements, the latest results support the idea that ‘new’ physics exists beyond the Standard Model. The findings were announced today at a special colloquium at Brookhaven National Laboratory in the US.

The Standard Model describes how quarks and leptons – a class of particles that includes elect
