A precise new KLOE measurement of $F_{\pi }$ with ISR events and determination of $\pi \pi$ contribution to $a_{\mu }$ for [0.35,0.95] GeV${}^2$

Abstract

The KLOE experiment at the DA$\Phi$NE $\varphi$-factory has performed a new precise measurement of the pion form factor using Initial State Radiation events, with photons emitted at small polar angle. Results based on an integrated luminosity of 240 pb${}^{-1}$ and extraction of the $\pi \pi$ contribution to $a_{\mu }$ in the mass range [0.35,0.95] GeV${}^2$ are presented, the systematic uncertainty is reduced with respect to the published KLOE result.
