Limit on the production of a low-mass vector boson in e+e−→Uγ, U→e+e− with the KLOE experiment

Limit on the production of a low-mass vector boson in e+e−→Uγ, U→e+e− with the KLOE experiment

The existence of a new force beyond the Standard Model is compelling because it could explain several striking astrophysical observations which fail standard interpretations. We searched for the light vector mediator of this dark force, the U boson, with the KLOE detector at the DAΦNE e+e− collider....
