The KLOE experiment is currently taking data at the electron‐positron collider DAΦNE, the Frascati φ‐factory.

Prospects for the entire sample and the feasibility to extend such a measurement down to threshold are presented.

Abstract
The KLOE experiment is currently taking data at the electron‐positron collider DAΦNE, the Frascati φ‐factory. At the end of this run, we expect to have integrated 2.5 fb−1 of collisions at center of mass energy W ∼ M φ. Large samples of light pseudoscalar and scalar mesons are produced through φ radiative decays. A summary of the measurements in progress on the previously collected 450 pb−1 allows us to quote the expectations on the entire sample. KLOE has also proven the feasibility of precise measurement of the hadronic cross‐section σ(e+e− → π+π−) in the region 0.33 < M2ππ < 1.02 GeV20.33 < Mππ2 < 1.02 GeV2 , extracting it by the measurement of the π+π−γ cross section at small photon angles. Prospects for the entire sample and the feasibility to extend such a measurement down to threshold are presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
