Branching ratio measurement of the $\pi^0$ Dalitz decay at NA62
An exploratory measurement of the branching ratio of the $\pi^0 \rightarrow e^+e^- \gamma$ decay using data taken during 2018 by NA62, a fixed target kaon decay experiment based at CERN, is presented. The total number of signal events observed is 112,711 and the branching ratio was measured to be ($...
