چکیده
We propose a simple model of dark matter and CP violation consider the associated triple quadruple productions 125 GeV Higgs bosons at Large Hadron Collider (LHC). In model, is vector-like fermion $(\bar{\chi}, \chi)$ interacting with Standard Model only through complex messenger scalar $S$ which an electroweak singlet. New sources reside in most general potential involving doublet $H$ singlet $S$, as well Yukawa coupling between \chi)$. study current experimental constraints from measurements, searches for new scalars LHC, precision EDM relic density, direct indirect detections matter. A smoking-gun signature could come Higgs-to-Higgs decays, $h_3\to h_2h_1$, where $h_3/h_2/h_1$ are heaviest scalar, second SM-like 125-GeV Higgs, respectively. Taking into account other such 2h_2$ $h_3/h_2\to 2h_1$, then gives rise to novel $3h_1$ $4h_1$ final states, have yet be searched experimentally. present four benchmarks show event rates states large ${\cal O}(10)\ {\rm fb}$ O}(1)\ fb}$, respectively, 14-TeV LHC. This work opens up frontier searching high energy collider.

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 کاملHadronic uncertainties and isospin violation in supersymmetric dark matter models
Current limits from dark matter direct-detection experiments place a powerful constraint on the parameter space of the Minimal Supersymmetric Standard Model (MSSM). The interpretation of these limits, however, depends sensitively on the hadronic uncertainties associated with the scattering of supersymmetric dark matter particles off nucleons. For spin-independent scattering, we review the role ...
متن کاملDark-matter-induced violation of the weak equivalence principle.
A long-range fifth force coupled to dark matter can induce a coupling to ordinary matter if the dark matter interacts with standard model fields. We consider constraints on such a scenario from both astrophysical observations and laboratory experiments. We also examine the case where the dark matter is a weakly interacting massive particle, and derive relations between the coupling to dark matt...
