Dark Photon Hunt (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption This chart shows the search area (green) explored in an analysis of BaBar data where dark photon particles have not been found, compared with other experiments' search areas. The red band shows the favored search area to show whether dark photons are causing the so-called "g-2 anomaly," and the white areas are among the unexplored territories for dark photons.
