New Constraints on “ Cool ” Dark Matter
It has been suggested that a sterile neutrino ν s which mixes with standard neutrinos can form nonthermal " cool " Dark Matter if its mass and mixing angle fall in the ranges 0.1 keV < ∼ m s < ∼ 10 keV and 10 −10 < ∼ sin 2 θ < ∼ 10 −4 , respectively. We point out that the required mixing makes these heavy neutrinos unstable. The dominant decay mode is into three light neutrinos, but the most st...
متن کاملTheory, phenomenology, and prospects for detection of supersymmetric dark matter.
One of the great attractions of minimal super-unified supersymmetric models is the prediction of a massive, stable, weakly interacting particle (the lightest supersymmetric partner, LSP) which can have the right relic abundance to be a cold dark matter candidate. In this paper we investigate the identity, mass, and properties of the LSP after requiring gauge coupling unification, proper electro...
متن کاملDirect detection constraints on dark photon dark matter
Article history: Received 20 January 2015 Received in revised form 7 May 2015 Accepted 10 June 2015 Available online 11 June 2015 Editor: A. Ringwald Dark matter detectors built primarily to probe elastic scattering of WIMPs on nuclei are also precise probes of light, weakly coupled, particles that may be absorbed by the detector material. In this paper, we derive constraints on the minimal mod...
متن کاملProspects for Indirect Detection of Neutralino Dark Matter
Dark matter candidates arising in models of particle physics incorporating weak scale supersymmetry may produce detectable signals through their annihilation into neutrinos, photons, or positrons. A large number of relevant experiments are planned or underway. The ‘logically possible’ parameter space is unwieldy. By working in the framework of minimal supergravity, we can survey the implication...
متن کاملProspects for direct dark matter detection in the Constrained MSSM
We outline the WIMP dark matter parameter space in the Constrained MSSM by performing a comprehensive statistical analysis that compares with experimental data predicted superpartner masses and other collider observables as well as a cold dark matter abundance. We include uncertainties arising from theoretical approximations as well as from residual experimental errors on relevant Standard Mode...
