Two-photon physics at KLOE/KLOE-2

Studies of γγ interactions are performed with the KLOE detector, without tagging of the outgoing e+e−. The data sample is from an integrated luminosity of 240pb−1 collected at the ϕ-factory DAΦNE with e+e− beams colliding at , below the ϕ resonance peak. We present preliminary results concerning the measurement of the σe+e−→e+e−η cross section, using the η→π+π−π0 and η→3π0 channels, leading to consistent values, as well as the analysis of the four photon invariant mass, showing the contribution of the e+e−→e+e−π0π0 process in the small mass region of the spectrum. A brief status of the KLOE-2 e± taggers is reported.
