3. Study of the one-way speed of light anisotropy with particle beams

Abstract

Concepts of high precision studies of the one-way speed of light anisotropy are discussed. The high energy particle beam allows measurement of a one-way speed of light anisotropy (SOLA) via analysis of the beam momentum variation with sidereal phase without the use of synchronized clocks. High precision beam position monitors could provide accurate monitoring of the beam orbit and determination of the particle beam momentum with relative accuracy on the level of 10−10, which corresponds to a limit on SOLA of 10−18 with existing storage rings. A few additional versions of the experiment are also presented.

7. An electron fixed target experiment to search for a new vector boson A′ decaying to e+e−.

Author

Abstract

We describe an experiment to search for a new vector boson A′ with weak coupling α′ ≳ 6 × 10−8α to electrons (α = e2/4π) in the mass range 65 MeV < mA′ < 550 MeV. New vector bosons with such small couplings arise naturally from a small kinetic mixing of the “dark photon” A′ with the photon — one of the very few ways in which new forces can couple to the Standard Model — and have received considerable attention as an explanation of various dark matter related anomalies. A′ bosons are produced by radiation off an electron beam, and could appear as narrow resonances with small production cross-section in the trident e+e− spectrum. We summarize the experimental approach described in a proposal submitted to Jefferson Laboratory’s PAC35, PR-10-009 [1]. This experiment, the A′ Experiment (APEX), uses the electron beam of the Continuous Electron Beam Accelerator Facility at Jefferson Laboratory (CEBAF) at energies of ≈ 1–4 GeV incident on 0:5 − 10% radiation length Tungsten multi-foil targets, and measures the resulting e+e− pairs to search for the A′ using the High Resolution Spectrometer and the septum magnet in Hall A. With a ∼ 1 month run, APEX will achieve very good sensitivity because the statistics of e+e− pairs will be ∼ 10,000 times larger in the explored mass range than any previous search for the A′ boson. These statistics and the excellent mass resolution of the spectrometers allow sensitivity to α′/α one to three orders of magnitude below current limits, in a region of parameter space of great theoretical and phenomenological interest. Similar experiments could also be performed at other facilities, such as the Mainz Microtron. [ABSTRACT FROM AUTHOR]
