Neutral pion lifetime measurements and the QCD chiral anomaly
A fundamental property of QCD is the presence of the chiral anomaly, which is the dominant component of the π[superscript 0]→γγ decay rate. Based on this anomaly and its small (≃4.5%) chiral correction, a prediction of the π[superscript 0] lifetime can be used as a test of QCD at confinement scale e...
