Searches for a light Higgs and dark photons at BABAR

A light CP-odd Higgs Boson (A0) is predicted in extensions to the Standard Model such as Next-to-Minimal Supersymmetry Standard Model (NMSSM). We search for υ(1S) → γA0; A0 → μ+μ− or τ+τ− and υ(2S,3S) → γA0; A0 → hadrons at BaBar using a sample of 122M υ(3S), 99M υ(2S), and 23M υ(1S). We see no evidence of an NMSSM A0. We also search for dark photons A' in e+e− → A'h'; h' → A'A'. We see no evidence of an A' with 516pb−1 of data
