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…
