We search for single-photon events in 53 fb^-1 of e+e- collision data collected with the BaBar detector at the PEP-II B-factory. We look for events with a single high-energy photon and a large missing momentum and energy, consistent with production of a spin-1 particle A' through the process e+e->gamma A', A'->invisible. Such particles, referred to as "dark photons", are motivated by theories applying a U(1) gauge symmetry to dark matter. We find no evidence for such processes and set 90% confidence level upper limits on the coupling strength of A' to e+e- in the mass range m_A'<=8 GeV. In particular, our limits exclude the values of the A' coupling suggested by the dark-photon interpretation of the muon (g-2) anomaly, as well as a broad range of parameters for the dark-sector models.

Dark Higgs-strahlung at Belle II: A distinctive dark sector signature with displaced vertices and missing energy
Dark Higgs-strahlung, with or without an initial-state photon, gives a displaced-vertex plus missing-energy signature that could make Belle II more sensitive to dark photon models than single-photon searches alone.

Searching for long-lived ALPs with a laser-assisted optical dump
A laser-assisted optical dump could probe ALP-electron couplings down to ~10^-6 (10^-7) GeV^-1 with 16.5 (125) GeV electron beams, and when both couplings are present the Primakoff process improves the electron-coupli...
