Investigation at a φ-factory can shed light on several debated issues in particle physics. We
discuss:(i) recent theoretical development and experimental progress in kaon physics …

The broad physics program of the KLOE experiment is based on the high event rate at the
Frascati φfactory, and calls for an up-to-date system for data acquisition and processing. In …

We present a new limit on the production of a light dark-force mediator with the KLOE
detector at DAΦNE. This boson, called U, has been searched for in the decay ϕ→ ηU, U→ …

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 …

The existence of a light dark force mediator has been tested with the KLOE detector at
DAΦNE. This particle, called U, is searched for using the decay chain ϕ→ ηU, η→ π+ π− π0 …

We have measured the cross section of the radiative process e+ e−→ π+ π− γ with the KLOE
detector at the Frascati ϕ-factory DAΦNE, from events taken at a CM energy W= 1 GeV …

We have measured the cross section σ (e+ e−→ π+ π− γ (γ)) at DAΦNE, the Frascati ϕ-
factory, using events with initial state radiation photons emitted at small angle and inclusive …

We have searched for a light vector boson U, the possible carrier of a “dark force”, with the
KLOE detector at the DAΦNE e+ e− collider, motivated by astrophysical evidence for the …

We have measured the cross section σ (e+ e−→ π+ π− γ) at an energy W= mϕ= 1.02 GeV
with the KLOE detector at the electron–positron collider DAΦNE. From the dependence of …

The recent interest in a light gauge boson in the framework of an extra U (1) symmetry
motivates searches in the mass range below 1 GeV. We present a search for such a particle …
