We have measured the cross section of radiative process e+e- -> pi+pi-gamma with KLOE detector at Frascati phi-factory DAPHNE, from events taken a CM energy W=1 GeV. Initial state radiation allows us to obtain for pi+pi-, pion form factor |F_pi|^2 and dipion contribution muon magnetic moment anomaly, Delta a_mu^{pipi} = (478.5+-2.0_{stat}+-5.0_{syst}+-4.5_{th}) x 10^{-10} in range 0.1 < M_{pipi}^2 0.85 GeV^2, where theoretical error includes SU(3) ChPT estimate uncertainty on photon final...

The existence of a new force beyond the Standard Model is compelling because it could explain several striking astrophysical observations which fail standard interpretations. We searched for light vector mediator this dark force, $\mathrm{U}$ boson, with KLOE detector at DA$\Phi$NE $\mathrm{e}^{+}\mathrm{e}^{-}$ collider. Using an integrated luminosity 1.54 fb$^{-1}$, we studied process $\mathrm{e}^{+}\mathrm{e}^{-} \to \mathrm{U}\gamma$, $\mathrm{U} \mathrm{e}^{+}\mathrm{e}^{-}$, using...

We have searched for a light vector boson U, the possible carrier of "dark force", with KLOE detector at DAΦNE e+e− collider, motivated by astrophysical evidence presence dark matter in Universe. Using collisions collected an integrated luminosity 239.3 pb−1, we look dimuon mass peak reaction e+e−→μ+μ−γ, corresponding to decay U→μ+μ−. find no U signal. set 90% CL upper limit mixing parameter squared between photon and 1.6×10−5 8.6×10−7 region 520<mU<980 MeV.

The recent interest in a light gauge boson the framework of an extra U(1) symmetry motivates searches mass range below 1 GeV. We present search for such particle, dark photon, e+e−→Uγ, U→π+π− based on 28 million e+e−→π+π−γ events collected at DAΦNE by KLOE experiment. π+ π− production initial-state radiation compensates loss sensitivity previous U→e+e−, μ+μ− due to small branching ratios ρ–ω resonance region. found no evidence signal and set limit 90% CL mixing strength between photon ε2, U...

Neutral kaon pairs produced in phi decays anti-symmetric entangled state can be exploited to search for violation of CPT symmetry and Lorentz invariance. We present an analysis the CP-violating process phi->K_S K_L->pi+pi-pi+pi- based on 1.7 fb-1 data collected by KLOE experiment at Frascati phi-factory DAFNE.

A bstract The three precision measurements of the cross section σ ( e + − → π γ(γ)) using initial state radiation by KLOE collaboration provide an important input for prediction hadronic contribution to anomalous magnetic moment muon. These are correlated both statistical and systematic uncertainties and, therefore, simultaneous use these requires covariance matrices that fully describe correlations. We present construction them determine a combined measurement γ(γ)). find, from this...

We describe the KLOE detector at DAFNE, and its physics program. The impact of our results on flavor hadron to date, as well an outlook for further improvement in near future, are discussed.

We have studied the phi->a_0(980) gamma process with KLOE detector at Frascati phi-factory DAPhNE by detecting phi->eta pi^0 decays in final states eta->gamma and eta->pi^+ pi^- pi^0. measured branching ratios for both states: Br(phi->eta gamma)=(7.01 +/- 0.10 0.20)x10^-5 (7.12 0.13 0.22)x10^-5 respectively. also extracted a_0(980) mass its couplings to eta pi^0, K^+ K^-, phi meson from fit of invariant distributions using different phenomenological models.
