Limit on the production of a new vector boson in $e^{+} e^{-} \to U γ$ , U $\to π^{+} π^{-}$ with the KLOE experiment

2 Collaboration, A. Anastasi, D. Babusci +62

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, the…

Limit on the production of a low-mass vector boson in $e^{+} e^{-} \to U γ$ , $U \to e^{+} e^{-}$ with the KLOE experiment

A. Anastasi, D. Babusci, G. Bencivenni +61

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 se…
