D JO - Physical Review D SP - 011102 EP - 7pp VL - 94 IS - 1 PB - Amer Physical Soc AB - Many models of physics beyond the standard model predict the existence of new Abelian forces with new gauge bosons mediating interactions between "dark sectors" and the standard model. We report a search for a dark boson Z' coupling only to the second and third generations of leptons in the reaction e(+)e(-) -> mu(+)mu(-) Z', Z' -> mu(+)mu(-) using 514 fb(-1) of data collected by the BABAR experiment. No significant signal is observed for Z' masses in the range 0.212-10 GeV. Limits on the coupling parameter g' as low as 7 x 10(-4) are derived, leading to improvements in the bounds compared to those previously derived from neutrino experiments.
