This talk gives an overview of the DarkLight experimental concept: a search for a heavy photon A′ in the 10-90 MeV/c2 mass range. After briefly describing the theoretical motivation, the talk focuses on the experimental concept and design. Topics include operation using a half-megawatt, 100 MeV electron beam at the Jefferson Lab FEL, detector design and performance, and expected backgrounds estimated from beam tests and Monte Carlo simulations.

    Electron beam induced current (EBIC) is often used to evaluate minority carrier properties in semiconductors. Various mathematical models have been proposed; the most advanced is that of Bonard and Ganière [J. Appl. Phys. 79, 6987 (1996)]. However, in order to apply this model to EBIC...

    The A' EXperiment (APEX) is designed to search for new vector bosons that have small couplings to charged particles. Such vectors can arise naturally from a small kinetic mixing of a new "dark photon" (A') with the photon - one of the very few ways in which new forces can couple to the Standard...

    Light extra U(1) gauge bosons, so called hidden photons, which reside in a hidden sector have attracted much attention since they are a well motivated feature of many scenarios beyond the Standard Model and furthermore could mediate the interaction with hidden sector dark matter. We review...
