Dark Matter in Minimal Trinification
نویسندگان
چکیده
We study an example of Grand Unified Theory (GUT), known as trinification, which was first introduced in 1984 by S.Glashow. This model has the GUT gauge group as [SU(3)] with a discrete Z3 to ensure the couplings are unified at the GUT scale. In this letter we consider this trinification model in its minimal formulation and investigate its robustness in the context of cosmology. In particular we show that for a large set of the parameter space the model doesn’t seem to provide a Dark Matter candidate compatible with cosmological data. ∗ Article based on research supported by the US Department of Energy (grant DE–FG02– 06ER41418)

Mssm from Susy Trinification
We construct a SU(3) supersymmetric gauge theory with a common gauge coupling g using only fields belonging to 27, 27 and singlet representations of E6. Spontaneous breaking of this gauge group at a scale MX = 1.3× 10 GeV gives naturally rise exactly to the Minimal Supersymmetric Standard Model (MSSM) and consequently to the experimentally favored values of sinθw and αs.The gauge hierarchy prob...
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...

We consider the Standard Model extended with a dark matter particle in curved spacetime, motivated by the fact that the only current evidence for dark matter is through its gravitational interactions, and we investigate the impact on the dark matter stability of terms in the Lagrangian linear in the dark matter field and proportional to the Ricci scalar. We show that this “gravity portal” induc...

متن کاملDark Matter in the Finely Tuned Minimal Supersymmetric Standard Model
We explore dark matter in the Finely Tuned Minimal Supersymmetric Standard model recently proposed by Arkani-Hamed and Dimopoulos. Relative to the MSSM, there are fewer particles at freezeout, so the calculation of the relic abundance simplifies. Similarly, the predictions for direct detection of the dark matter sharpen. There is a large region of mixed bino–higgsino dark matter where the light...
