Electromagnetic decays of the neutral pion

We complement studies of the neutral pion transition form factor ${\ensuremath{\pi}}^{0}\ensuremath{\rightarrow}{\ensuremath{\gamma}}^{(*)}{\ensuremath{\gamma}}^{(*)}$ with calculations for the electromagnetic decay widths of the processes ${\ensuremath{\pi}}^{0}\ensuremath{\rightarrow}{e}^{+}{e}^{\...
