The neutron electromagnetic form factors in the time-like region
No full textThe final results of the FENICE experiment on the first measurement of the neutron time-like form factors are presented. Results on the proton time-like form factors and on the multihadronic cross-section are also reported. Finally a first proposal by the FENICE Collaboration to perform a new measurement of the neutron form factors is briefly discussed
Kloe first results on hadronic physics
No full textThe KLOE experiment has collected 2.4 pb(-1) of integrated luminosity during the 1999 data-taking. This data sample has been used to study the radiative decays of the phi (1020) meson: phi --> pi (0)pi (0)gamma, pi (+)pi (-)gamma, eta pi (0)gamma and phi --> eta gamma, eta'gamma. The preliminary results are reported in this paper. The analysis of the Dalitz plot of the decay phi --> pi (+)pi (-)pi (0) is also presented

phi->eta e+e- and phi->pi0e+e-, and the eta and pi0pi0 production in gamma gamma collisions are reported. Prospects for the KLOE-2 data-taking are also
presented
Radiative Phi decays at KLOE
No full textWe describe the status of the analyses in progress on light meson spectroscopy in the KLOE
experiment. We present the analyses of f decays into f0 980

. All the presented results
are based on a sample of about 450 pb

data taking. From the 2004-2005 data taking a factor 5 improvement in the integrated luminosity
is expected
Light scalar mesons at KLOE
No full textThe scalar mesons of mass below 1 GeV have been studied with the KLOE detector at the Frascati -factory DANE, through the radiative decays of the (1020). The f 0(980) has been studied in the decays ! 0 0 and ! +− looking also for a possible signal of the (600), while for the a0(980) the ! 0 decay has been exploited. The branching ratios of these decays have been measured, and the relevant parameters of the scalar mesons have been extracted from the fit of the invariant masses of the pseudoscalar mesons in the final states. Furthermore an upper limit for the branching ratio of !(a0/ f0)!K0 ̄K 0 has been obtained
