| Title | A SEARCH FOR A NEW GAUGE BOSON A' | ||||
| Abstract | In the Standard Model, gauge bosons mediate the strong, weak, and electromagnetic forces. New forces could have escaped detection only if their mediators are either heavier than order(TeV) or weakly coupled to charged matter. New vector bosons with small coupling a' arise naturally from a small kinetic mixing with the photon and have received considerable attention as an explanation of various dark matter related anomalies. Such particles can be produced in electron-nucleus fixed-target scattering and then decay to e+e- pairs. New light vector bosons and their associated forces are a common feature of Standard Model extensions, but existing constraints are remarkably sparse. The APEX experiment will search for a new vector boson A' with coupling a'/a_fs > 6 × 10^-8 to electrons in the mass range 65MeV < mass A' < 550MeV. The experiment will study e+e- production off an electron beam incident on a high-Z target in Hall A at Jefferson Lab. The e- and e+ will be detected in the High R | ||||
