Precision measurement of $\ddot{I}ƒ(e^{+}{e}^{-}\to \ddot{I}{€}^{+}\ddot{I}{€}^{-}{\hat{I}}^3)/\ddot{I}ƒ(e^{+}{e}^{-}\to \hat{I}{¼}^{+}\hat{I}{¼}^{-}{\hat{I}}^3)$ and determination of the $\ddot{I}{€}^{+}\ddot{I}{€}^{-}$ contribution to the muon anomaly with the KLOE detector

KLOE, KLOE-2 Collaborations, : +74

We have measured the ratio $\ddot{I}ƒ(e^{+}{e}^{-}\to \ddot{I}{€}^{+}\ddot{I}{€}^{-}{\hat{I}}^3)/\ddot{I}ƒ(e^{+}{e}^{-}\to \hat{I}{¼}^{+}\hat{I}{¼}^{-}{\hat{I}}^3)$, with the KLOE detector at DA$\hat{I}¦$NE for a total integrated luminosity of $\sim$ 240 pb…
