Singlet 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 کاملA Dark Matter Candidate from an Extra (Non-Universal) Dimension
We show that a recently constructed five–dimensional (5D) model with gauge– Higgs unification and explicit Lorentz symmetry breaking in the bulk, provides a natural dark matter candidate. This is the lightest Kaluza–Klein particle odd under a certain discrete Z2 symmetry, which has been introduced to improve the naturalness of the model, and resembles KK–parity but is less constraining. The dar...
متن کاملAxino as Cold Dark Matter Candidate
The possibility of the CDM axino is presented. From the early days of supersymmetry, axino has been considered as hot dark matter and warm dark matter. But the CDM axino has been considered quite recently. It is because the low reheating temperature of the universe is gaining momentum recently from various considerations in particle cosmology. I present a general introduction on the CDM’s, in p...
متن کاملLSP as a Candidate for Dark Matter
The most recent observations by the WMAP satellite provided us with data of unprecedented accuracy regarding the parameters describing the Standard Cosmological Model. The current matter-energy density of the Universe is close to its critical value of which 73 % is attributed to Dark Energy, 23 % to Cold Dark Matter and only 4 % is ordinary matter of baryonic nature. The origins of the Dark Ene...
متن کاملCold Dark Matter as Compact Composite Objects
Dark Matter (DM) being the vital ingredient in the cosmos, still remains a mystery. Standard assumption is that the collisionless cold dark matter (CCDM) particles are represented by some weakly interacting fundamental fields which can not be associated with any standard quarks or leptons. However, recent analyses of structure on galactic and sub-galactic scales have suggested discrepancies and...
