We present the results of several searches for dark photons produced in e+e- collisions and decaying into leptons, hadrons, or invisible final states.

Following recent puzzling astrophysical results and recent theoretical studies, a search for a
relatively low mass ( 1 GeV) new vector boson (the U), weakly coupled with SM particles and
decaying into leptons pairs, by using the Initial State Radiation (ISR) process, was performed at KLOE.
The KLOE experiment at the $\phi$ − factory DA$\Phi$NE is the first to have
exploited ISR to...

At BESIII, with 106 million psi(2S) events at BESIII, we have searched for a light Higgs-like boson A0 in the process psi(2S)-> pi+pi- J/psi, J/psi->\gamma A0, A0-> mu+mu-. We set 90% confidence level upper limits on
the product branching fractions for J/psi -> gammaA0, A0 -> mu+mu−
that range from 4 * 10^−7 to 2.1 * 10^−5, depending on the mass of A0, for M(A0) < 3.0 GeV/c2. Using J/psi->...
