CP Violation and Dark Matter
A brief review is given of the effects of CP violation on the direct detection of neutralinos in dark matter detectors. We first summarize the current developments using the cancellation mechanism which allows for the existence of large CP violating phases consistent with experimental limits on the electron and on the neutron electric dipole moments in a broad class of SUSY, string and D brane ...
متن کاملNeutralino dark matter in the MSSM with CP violation
In the MSSM, the presence of CP phases can have a significant impact on the neutralino relic abundance. These phase effects are on the one hand due to shifts in the masses, on the other hand due to modifications of the couplings. Typical variations in Ωh solely from modifications in the couplings are O(10%–100%).

متن کاملDark Matter, Dark Energy and the solution of the strong CP problem
The strong CP problem was solved by Peccei & Quinn by introducing axions, which are a viable candidate for Dark Matter (DM). Here the PQ approach is modified so to yield also Dark Energy (DE), which arises in fair proportions, without tuning any extra parameter. DM and DE arise from a single scalar field and, in the present ecpoch, are weakly coupled. Fluctuations have a fair evolution. The mod...
متن کاملIndirect detection imprint of a CP violating dark sector
We introduce a simple scenario involving fermionic dark matter (χ) and singlet scalar mediators that may account for the Galactic center GeV γ-ray excess while satisfying present direct detection constraints. CP violation in the scalar potential leads to a mixing between the Standard Model Higgs boson and the scalar singlet, resulting in three scalars, h1;2;3, of indefinite CP-transformation pr...
