ProbingCPviolation with the deuteron electric dipole moment

Abstract

We present an analysis of the electric dipole moment (EDM) of the deuteron as induced by CP- violating operators of dimension 4, 5 and 6 includingQCD, the EDMs and color EDMs of quarks, four-quark interactions and the Weinberg operator. We demonstrate that the precision goal of the EDM Collaboration's proposal to search for the deuteron EDM, (1 3)×10 27 ecm, will provide an improvement in sensitivity to these sources of one-two orders of magnitude relative to the existing bounds. We consider in detail the level to which CP-odd phases can be probed within the MSSM. The most stringent constraints on flavor-diagonal CP violation in the hadronic sector arise from bounds on the EDMs of the neutron (1), mercury (2), and in certain cases thallium (3). These experiments have important implications for physics beyond the Standard Model, and its supersymmetric extensions in particular (see e.g. (4)). In what follows, we will show that a proposed measure- ment of the deuteron EDM (5), with projected sensitivity
