The KLOE experiment has just collected 2.5 fb−1 of e + e − collisions at center of mass energy around the φ mass. Radiative decays are used to produce large statistical samples of light scala and pseudoscalar mesons. The analysis of the first 45

A coupled channels analysis, based on the K-matrix approach, is presented for photo-induced kaon production. It is shown that channel coupling effects are large and should not be ignored. The importance of contact terms in the analysis, associated wi

We have searched with the KLOE detector for the P and CP violating decay eta --> pi(+)pi(-) in a sample of 1.55 x 10(7) eta's from the decay phi --> etagamma of phi-mesons produced in e(+)e(-) annihilations at DAPhiNE. No signal is found. We obtain t

A single-spin asymmetry was measured in the azimuthal distribution of pi+pi- pairs produced in semi-inclusive deep-inelastic scattering on a transversely polarized hydrogen target. For the first time, evidence is found for a correlation between the t
