Positrons at Jefferson Laboratory
We review the compelling case for establishing a capability to accelerate positrons at Jefferson Lab. The potential appplications range from the study of two-photon exchange and deeplyvirtual Compton scattering to exploiting the charge current weak interaction to probe the flavor structure of hadrons and nuclei. There are also fascinating ideas for using such a capability to discover new physic...
متن کاملSearching for a Heavy Photon and Hidden Sectors with the Heavy Photon Search Experiment
In recent years, astrophysical anomalies have led to new theories to extend the Standard Model to include an additional gauge boson called the heavy photon (or A′), which would mediate a new force between dark matter particles and explain these anomalies. In addition to dark matter, it is possible that there exists an entire hidden sector of particles that interact with this heavy photon, which...
متن کاملA Proposal for the DarkLight Experiment at the Jefferson Laboratory Free Electron Laser
New theories of dark matter predict A gauge bosons in the mass range of 0.01– 10 GeV that couple to charged fermions with a strength of α /α EM = 10 −4 of the photon or less. We propose to design, construct and operate an experiment called DarkLight (Detecting A Resonance Kinematically with eLectrons Incident on a Gaseous Hydrogen Target) to use the 1 MW 100 MeV electron beam at the Jeffer-son ...
متن کاملHeavy Photon Search
The Heavy Photon Search Experiment (HPS) is a new experiment at Jefferson Lab designed to look for massive vector gauge bosons (heavy photons) in the mass range 20-1000 MeV/c which couple to electrons with couplings α/α in the range 10 to 10 . The experiment utilizes a compact forward spectrometer employing silicon microstrip detectors for vertexing and tracking and a PbWO4 electromagnetic calo...
متن کاملThe Cryogenic Target for the G Experiment at Jefferson Lab
A cryogenic horizontal single loop target has been designed, built, tested and operated for the G0 experiment in Hall C at Jefferson Lab. The target cell is 20 cm long, the loop volume is 6.5 l and the target operates with the cryogenic pump fully immersed in the fluid. The target has been designed to operate at 30 Hz rotational pump speed with either liquid hydrogen or liquid deuterium. The hi...
