| Summary: | The 3.5 standard deviation discrepancy between the standard model prediction for the muon anomalous magnetic moment g−2 and the corresponding experimental measurementis one of the most intriguing potential signals for physics beyond the standard model. The largest uncertainty in the standard model prediction for the muon g − 2 arises from uncertainties in the measured low-energy e+e− → hadrons cross sections. New cross section results from the Babar experiment at SLAC for e+ e− → π+π−π0π0 and for e+e− → KKππ channels are presented that significantly reduce some of the uncertaintiesin the standard model prediction for the muon g − 2. |
