摘要
The KLOE experiment has collected 2.5 fb(-1) of e(+) e(-)collisions at the f peak and about 300 pb(-1) in the center-of-mass energy region 1000-1030MeV. Data taken on peak are used to study the properties of light scalar and pseudoscalar mesons, produced through phi radiative decays, and to precisely measure the pion form factor using Initial State Radiation events. Energy scan data are used to measure the cross-section of the process e(+) e(-) -> omega pi(0) as a function of the center-of-mass energy and to perform a preliminary study of the reaction e(+) e(-) -> e(+) e(-) pi(0) pi(0).
