There is a worldwide race in the search for dark photons and dark
Higgs particles. (Here is a background article in
Science Magazine of March 23 2017). If dark photons(dark Higgs) were observed,
they would revolutionize our understanding of the fundamental structures
and interactions of our universe. There is a unique opportunity
today at Fermilab to search directly for dark photon and dark Higgs
production in highly motivated parameter space in high-energy
proton-nucleus collisions using the existing SeaQuest(E906/E1039/E1027)
dimuon spectrometer. This search can be accomplished with parasitic data
taking with the upcoming E1039 experiment. The resulting data would
provide the world's best sensitivity to darkphoton(darkHiggs) masses between
0.2-10 GeV/c2 for the next decade. Only a relatively minor upgrade of the
existing SeaQuest dimuon spectrometer and trigger system
is required to improve the acceptance and reduce the trigger rate to an
acceptable level.
