Many models of New Physics postulate the existence new gauge bosons mediating interactions between “dark sectors” and the Standard Model. We present a search for a dark boson Z' coupling only to the second and third generation of leptons in the reaction e+e- -> mu+mu-Z', Z' -> mu+mu- with the full BABAR dataset. No significant signal is observed and limits improving upon bounds derived from neutrino experiments are set.
