Description
We have searched for a new neutral gauge vector boson (U boson)
in phi(1020) to eta e+e- decays, using about 1.8 fb-1 of data
collected by the KLOE detector. The present analysis is based on
an identication of the eta meson by its decays into three
neutral pions, which provides a sample about twice larger than the
one used in our previously published result.
The limit on U boson production is improved accordingly.
