The KLOE Experiment at the $phi$ factory DA$Phi$NE, has measured the cross section $sigma(e^+e^-topi^+pi^-gamma)$ using two different selection schemes: requiring the photon emission at small polar angle and detecting the photon at large polar angle in the calorimeter. Using a theoretical radiator function we extract the pion form factor and obtain the $pipi$ contribution to the anomalous magnetic moment of the muon. Results presented here come from the analysis of 240 pb^{-1} collected in 2002, with improved systematic uncertainty with respect to the published KLOE analysis. We also include an update of the previous analysis.
The KLOE experiment at the DA$Phi$NE $phi$-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$^{
Using a data set of 2.93 fb$^{-1}$ taken at a center-of-mass energy $sqrt{s}$ = 3.773 GeV with the BESIII detector at the BEPCII collider, we perform a search for an extra U(1) gauge boson, also denoted as a dark photon. We examine the initial state
In a few months the KLOE-2 detector is expected to start data taking at the upgraded DA$rm{Phi}$NE $phi$-factory of INFN Laboratori Nazionali di Frascati. It aims to collect 25 fb$^{-1}$ at the $phi(1020)$ peak, and about 5 fb$^{-1}$ in the energy re
The KLOE Collaboration completed the full data taking on March 2006, acquiring 2.5 fb ^ -1 at the peak of the phi and other 240 pb ^ -1 off-peak. A new Collaboration is working on a new project, called KLOE-2, to refine and extend the KLOE physics pr
Working at a $phi$-factory, KLOE/KLOE-2 has collected a very large and clean sample of $eta$ decays, which allow to perform a variety of precision measurements. This report presents the recent results on the $eta$-meson decays from KLOE/KLOE-2 experi
