Light Scalar Top Quarks and Supersymmetric Dark Matter
A stable neutralino χ̃1, assumed to be the lightest supersymmetric particle, is a favored particle physics candidate for the cosmological Dark Matter. We study co– annihilation of the lightest neutralino with the lighter scalar top quark t̃1. We show that for natural values of the neutralino mass, ∼300 GeV, the χ̃1–t̃1 mass difference has to exceed ∼ 10 to 30 GeV if χ̃1 is to contribute significantl...
متن کاملA Fermionic Top Partner: Naturalness and the LHC
Naturalness demands that the quadratic divergence of the one-loop top contribution to the Higgs mass be cancelled at a scale below 1 TeV. This can be achieved by introducing a fermionic (spin-1/2) top partner, as in, for example, Little Higgs models. In this paper, we study the phenomenology of a simple model realizing this mechanism. We present the current bounds on the model from precision el...
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 کاملSinglet fermionic dark matter
We propose a renormalizable model of a fermionic dark matter by introducing a gauge singlet Dirac fermion and a real singlet scalar. The bridges between the singlet sector and the standard model sector are only the singlet scalar interaction terms with the standard model Higgs field. The singlet fermion couples to the standard model particles through the mixing between the standard model Higgs ...
متن کاملThe Search for a Heavy Vector - like Top Partner T → Zt Decay
This paper outlines the analysis searching for a vector-like top partner T → Zt decay. A number of leading theories of physics beyond the Standard Model suggest the existence of heavy vector-like quarks with masses on the TeV scale. The discovery of such a particle would provide insight into strong dynamics at the TeV scale, the Higgs Mechanism and the mass hierarchy problem. In this analysis, ...
