Dark matter and the early Universe: A review

Abstract: Dark matter represents currently an outstanding problem in both cosmology and particle physics. In this review we discuss the possible explanations for dark matter and the experimental observables which can eventually lead to the discovery of dark matter and its nature, and demonstrate the close interplay between the cosmological properties of the early Universe and the observables used to constrain dark matter models in the context of new physics beyond the Standard Model.

“…Hence, in order to obtain a physically and mathematically consistent picture of the Universe, two different approaches have been proposed, called the dark components model, and the dark gravity model, respectively. The dark components model [80][81][82][83][84] assumes that the Universe is filled with two (still mysterious) components, dark energy, and dark matter, respectively, components for which many proposals have been advanced. In the dark gravity approach it is assumed that the nature of the gravitational force changes on astrophysical (galactic) and cosmological scales, and that the standard Einstein equations, so successful at the level of the Solar System, must be replaced by a novel theory of gravity, like, for example, theories with geometry-matter coupling [38,41], or gravitational models built upon more general geometries than the Riemannian one.…”

“…There are of course a great deal of models and theories postulating a role for structures of extra spatial dimensions without any motivation in connection with dark matter (see for example [50,51]). There are also a large number of dark matter candidates proposed that make no use of extra-dimensional structures (see for example [1,2], [3] section 27, as well as the two previous subsections of this paper).…”

“…The observation of EW production of Z (→ νν)γ jj lays the groundwork for further investigation of this signature in looking for possible hints of BSM physics, based on interesting and well-motivated benchmark scenarios involving new dark matter (DM) candidate particles or a hidden sector of new particles coupling with the SM Higgs boson. The existence of DM is evident from astrophysical observations [11], although its connection with the SM is still unknown because it has only been observed through gravitational interactions. In this paper, the connection of DM with SM particles is explored by introducing a coupling with the 125 GeV Higgs boson.…”
