KLOE Perspectives for R-Measurements at DAFNE2

As a future upgrade of the Frascati phi factory DAPHNE an increase of the center-of-mass energy of the accelerator up to W=2GeV has been proposed (DAFNE2). In this case the hadronic cross section in the energy range between 1-2 GeV can be measured with the KLOE detector. The feasibility of these measurements and the impact on the hadronic contribution to the anomalous magnetic moment of the muon are discussed. The possibilities for an energy scan are compared with the radiative return technique, in which the accelerator is running at a fixed center-of-mass energy and ISR-events are taken to lower the invariant mass of the hadronic system.

KLOE Results on Rare K0 Decays

This paper describes the current neutral Kaon dataset and physics measurements of KLOE at DAFNE. A brief discussion on the prospects for detector upgrades and analysis of other K0 rare decays is also included.

Study of the Decay phi --> pi0 pi0 gamma with the KLOE Detector

We have measured the branching ratio BR(phi --> pi0 pi0 gamma) with the KLOE detector using a sample of ~5x10^7 phi decays. phi mesons are produced at DAFNE, the Frascati phi-factory. We find BR(phi --> pi0 pi0 gamma) = (1.09 +- 0.03 (stat) +- 0.05 (syst))x10^-4. We fit the two--pion mass spectrum to models to disentangle contributions from various sources.
