Searches for light CP-odd Higgs bosons and dark photons at BaBar

Recent results are presented on searches for light CP-odd Higgs bosons and dark photons using data from the BaBar experiment at the PEP II asymmetric energy e+e− collider. The light Higgs bosons are sought via their production in radiative ϒ(1S) decays and their subsequent decays to gg and final states. The search for dark photons A′ involves radiative production e+e−→γA′ with A′→e+e− or μ+μ−. No signals are observed.
