ABSTRACT: We have carried out a new direct search for the CP violating decay KS -> 3pi0
with 1.7 fb^-1 of e+e- collisions collected by the KLOE detector at the
phi-factory DAFNE. We have searched for this decay in a sample of about 5.9 x
10^8 KS KL events tagging the KS by means of the KL interaction in the
calorimeter and requiring six prompt photons. With respect to our previous
search, the analysis has been improved by increasing of a factor four the
tagged sample and by a more effective background rejection of fake KS tags and
spurious clusters. We find no candidates in data and simulated background
samples, while we expect 0.12 standard model events. Normalizing to the number
of KS -> 2pi0 events in the same sample, we set the upper limit on BR(KS ->
3pi0 < 2.6 x 10^-8 at 90% C.L., five times lower than the previous limit. We
also set the upper limit on the eta_000 parameter, |eta_000 | < 0.0088 at 90%
C.L., improving by a factor two the latest direct measurement.

ABSTRACT: We have measured the ratio σ ( e + e − → π + π − γ ) / σ ( e + e − → μ + μ − γ ) , with the KLOE detector at DAΦNE for a total integrated luminosity of ∼ 240 pb − 1 . From this ratio we obtain the cross section σ ( e + e − → π + π − ) . From the cross section we determine the pion form factor | F π | 2 and the two-pion contribution to the muon anomaly a μ for 0.592 < M π π < 0.975 GeV , Δ π π a μ = ( 385.1 ± 1.1 stat ± 2.7 sys + theo ) × 10 − 10 . This result confirms the current discrepancy between the Standard Model calculation and the experimental measurement of the muon anomaly.

ABSTRACT: We have measured the ratio σ ( e + e − → π + π − γ ) / σ ( e + e − → μ + μ − γ ) , with the KLOE detector at DAΦNE for a total integrated luminosity of ∼ 240 pb − 1 . From this ratio we obtain the cross section σ ( e + e − → π + π − ) . From the cross section we determine the pion form factor | F π | 2 and the two-pion contribution to the muon anomaly a μ for 0.592 < M π π < 0.975 GeV , Δ π π a μ = ( 385.1 ± 1.1 stat ± 2.7 sys + theo ) × 10 − 10 . This result confirms the current discrepancy between the Standard Model calculation and the experimental measurement of the muon anomaly.
