Abstract: 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 , , . No evidence is found in 1.5 fb−1 of data. The resulting exclusion plot covers the mass range , setting an upper limit on the ratio between the U boson coupling constant and the fine structure constant, , of at 90% C.L. for .
