Electric Dipole Moments and the Mass Scale of New T-Violating, P-Conserving Interactions
نویسنده
چکیده
We consider the implications of experimental limits on the permanent electric dipole moment (EDM) of the electron and neutron for possible new timereversal violating (TV) parity-conserving (PC) interactions. We show that the constraints derived from one-loop contributions to the EDM exceed previously reported two-loop limits by more than an order of magnitude and imply a lower bound on the new TVPC mass scale ΛTV PC of 150 TeV for new TVPC strong interactions. These results imply a value of 10−15 or smaller for the ratio of low-energy TVPC matrix elements to those of the residual strong interaction. 11.30.Er, 14.20.Dh, 14.60.Cd Typeset using REVTEX ∗National Science Foundation Young Investigator

متن کاملSearching for T-Violating, P-Conserving New Physics with Neutrons
The observance of parity conserving time reversal violation in light quark systems could signal the presence of physics beyond the Standard Model. I discuss the implications of low-energy time reversal tests for the existence of such T-violating, P-conserving (TVPC) interactions. I argue that searches for permanent electric dipole moments (EDM’s) and direct TVPC searches provide complementary i...

We construct the relationship between nonrenormalizable, effective , time-reversal violating (TV) parity-conserving (PC) interactions of quarks and gauge bosons and various low-energy TVPC and TV parity-violating (PV) observables. Using effective field theory methods , we delineate the scenarious under which experimental limits on permanent electric dipole moments (EDM's) of the electron, neutr...
متن کاملMicroscopic T-Violating Optical Potential: Implications for Neutron-Transmission Experiments.
We derive a T-violating P-conserving optical potential for neutron-nucleus scattering, starting from a uniquely determined two-body ρ-exchange interaction with the same symmetry. We then obtain limits on the T-violating ρ-nucleon coupling g ρ from neutron-transmission experiments in 165 Ho. The limits may soon compete with those from measurements of atomic electric-dipole moments.
