From Hadronic Cross Section to the measurement of the Vacuum Polarization at KLOE: a fascinating endeavour

Graziano Venanzoni

The KLOE experiment at the $\varphi -factory$ DA$\Phi$NE in Frascati is the first to have employed Initial State Radiation (ISR) to precisely determine the $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}(\gamma )$ cross section…
