Proposal

The proton EDM (pEDM) proposal to DOE, for a storage ring proton EDM experiment with sensitivity 10^-29 e·cm, is available here: The proton EDM proposal is available from the EDM internal web page proton EDM proposal (2011). Polarized protons at their magic momentum of 0.7 GeV/c are stored in an all-electric storage ring, while high efficiency internal polarimeters monitor the proton transverse spin components as a function of time.

The deuteron EDM (dEDM) proposal as submitted to the BNL PAC in April 2008 is given here: 2008 deuteron_EDM_proposal.

The proposal to the Brookhaven Program Advisory Committee submitted in August 2004 can be found in deuteron_EDM_proposal (2004).

The proton and deuteron EDM experiments at 10^-29 e·cm are 10³ to 10⁴ times better than current EDM limits in terms of sensitivity to quark and gluon EDM, and the QCD theta parameter. They probe CP-violation at a range predicted by speculative theories beyond the standard model. The proton, deuteron and neutron EDM searches are complementary and combined together they will provide the source of the CP-violation if a non-zero EDM value is found in any of them. If CP-violation is found at that level they could shed light on the Baryon/anti-Baryon asymmetry mystery of our universe (BAU).

One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven Science Associates, a limited-liability company founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit, applied science and technology organization.
