“…In figures 3 and 4, we show similar constraints from the neutron and proton EDMs respectively assuming a factor of 10 3 improvement in current limit for the neutron EDM, i.e. d n < 1.8 × 10 −29 e • cm and a prospective limit on d p of order O(10 −29 ) e • cm [133], or approximately a factor of 2 × 10 4 improvement for the proton EDM. Currently limits from these EDMs would not permit us to set any constraints on the parameter space, and only with an improvement by a factor of about 10 3 will see comparable constraints to that imposed by d e .…”

We revisit the calculation of the electron, neutron, and proton electric dipole moments (EDMs) in the constrained minimal supersymmetric standard model (CMSSM). The relatively large mass of the Higgs boson, mH ≃ 125 GeV coupled with the (as yet) lack of discovery of any supersymmetric particle at the LHC, has pushed the supersymmetry breaking scale to several TeV or higher. Though one might expect this decoupling to have relaxed completely any bounds on the two CP violating phases in the CMSSM (θμ and θA), the impressive experimental improvements in the limits on the EDMs (particularly the electron EDM) still allow us to set constraints of order (0.01−0.1)π on θA and (0.001−0.1)π on θμ. We also discuss the impact of future improvements in the experimental limits on supersymmetric models.

“…[110]. There is a proposal to reach a precision on the proton EDM d p < 10 −29 e cm using the proton storage ring within the next decade [118], which would be a big improvement over the current neutron EDM constraint. This may lead to an improvement by 10 3 in constraints on CP -odd Hgg, Huū, and Hd d couplings, and potentially to an improvement by 10 6 in constraints on corresponding f HX CP .…”

The search for CP violation in interactions of the Higgs boson with either fermions or bosons provides attractive reference measurements in the Particle Physics Community Planning Exercise (a.k.a. "Snowmass"). Benchmark measurements of CP violation provide a limited and well-defined set of parameters that could be tested at the proton, electron-positron, photon, and muon colliders, and compared to those achieved through study of virtual effects in electric dipole moment measurements. We review the current status of these CP -sensitive studies and provide projections to future measurements. ContentsI. Introduction II. Framework of the Higgs CP study for Snowmass III.

“…Proton storage rings can achieve exquisite precision on the precession [15,16], making them are ideal targets for measuring these couplings. The recent advances in measurement of electron EDMs (see [17] for a recent review) may also be leveraged to provide the strongest lab-based limits on axionelectron couplings.…”

We consider different types of storage rings as precision probes of axion-mediated monopoledipole forces. We show that current and planned experiments aiming to measure magnetic and electric dipole moments of protons, muons and electrons very precisely may explore new parts of the parameter space beyond existing laboratory bounds and, in some case, beyond astrophysical constraints. Remarkably, a light axion coupled to muons may explain the FNAL/BNL (g − 2) µ anomaly as an environmental effect -the coherent axion field generated by the earth nucleons induces an extra contribution to the anomalous precession frequency of the muon explaining the discrepancy with respect to the SM prediction.
