Measurement of the π⁰ electromagnetic transition form factor
We present the result of a measurement of the π⁰ electromagnetic transition form factor in the time-like region of momentum transfer. From a data sample of roughly 100,000 π⁰ → e⁺ e⁻ γ decays, observed in the SINDRUM I magnetic spectrometer at the Paul Scherrer Institute (Switzerland), we measure a...
