Dark Photon Searches Using Displaced Vertices at Low Energy Colliders

Figure 1

Excluded region in the plane resulting from presently available data. Electron beam dump experiment covers the region of low masses and very low couplings, down to ~ . For higher masses and lower couplings limits come mainly from meson decays and electron-nucleon scattering experiments and to B-factories data (plot courtesy of S. Andreas). The plot reports also the projections for the experiments presently under construction. For details on single experiments see [39].
