The CP violation and scalar dark matter in a 331 model

چکیده
The 331 model with right-handed neutrinos is reassessed to investigate the CP violation in quark sector. After spontaneous symmetry breaking, masses and physical fields of particle content are obtained. fermions enlarged include exotic quarks known electric charge defined at TeV scale. existence these induces extra violations via couplings Standard Model mediated by charged gauge boson mass fixed An discrete [Formula: see text] introduced get a stable scalar field that can be candidate dark matter content. new interacts tree level works as portal. relic density associated calculated yield solution satisfies observed matter. region allowed on parameter space versus obtained bounds PANDAX2017, XENON1T(2t.y) LUX experiments.

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 کاملSinglet scalar dark matter in noncommutative space
In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered, but our information about the nature of dark matter is still limited. There are such particle candidates as scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...

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 کاملLepton flavor changing processes and CP violation in the 331 model
By extending the electroweak gauge group to SU(3)L×U(1)Y , the 331 model incorporates dilepton gauge bosons Y which do not respect individual lepton family number. We point out that, in addition to family diagonal couplings such as Y –e–e that change lepton family number by two units, dileptons may also have family non-diagonal couplings such as Y –μ–e. The latter coupling violates lepton famil...
