چکیده
A bstract We generalize the recently proposed continuum dark matter model to case where consists of a spin-1/2 or spin-1 gapped continuum. construct simple analogs weakly interacting massive particles annihilating through Z portal. discuss all existing experimental constraints, with strongest bounds arising from indirect detection and limits on decays cosmic microwave background. Our models are phenomenologically viable for gap scales 60–200 GeV (spin-1/2) 35–90 (spin-1), owing strong kinematic suppression direct which is unique states. comment future prospects suggest directions further building.

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 کاملThe Hot Dark Matter
There is a puzzling contradiction: direct observations favor a low-mass-density universe (0.2 ≤ Ωm ≤ 0.6), but the only model which fits universe structure over more than three orders of magnitude in distance scale has a mix of hot (neutrino) and cold dark matter providing a critical density universe. Models of an open universe (low Ωm) or one adding a cosmological constant (Λ) to provide a cri...
متن کاملThe DARK MATTER problem
There are several dark matter problems, each on a different scale. The standard way to prove the existence of dark matter is to compare dynamical estimates of the mass of an object (galaxy, cluster) with an evaluation of its population contents. Historically, we can distinguish four distinct problems : 1. the galactic force law in the solar neighbourhood 2. galactic halos 3. groups and clusters...
متن کاملThe dark matter crisis
I explore several possible solutions to the “missing satellites” problem that challenges the collisionless cold dark matter model.
متن کاملThe Dark Matter Telescope
Weak gravitational lensing enables direct reconstruction of dark matter maps over cosmologically significant volumes. This research is currently telescopelimited. The Dark Matter Telescope (DMT) is a proposed 8.4 m telescope with a 3◦ field of view, with an etendue of 260 m deg, ten times greater than any other current or planned telescope. With its large etendue and dedicated observational mod...
