Unification of Dark Energy and Dark Matter
We propose a scenario in which dark energy and dark matter are described in a unified manner. The ultralight pseudo-Nambu-Goldstone (pNG) boson, A, naturally explains the observed magnitude of dark energy, while the bosonic supersymmetry partner of the pNG boson, B, can be a dominant component of dark matter. The decay of B into a pair of electron and positron may explain the 511 keV γ ray from...
متن کاملBaryon Asymmetry and Dark Matter
We study the implications of a large baryogenesis temperature, TB = O(10 10 GeV), on the mass spectrum of superparticles in supersymmetric extensions of the standard model. Models with a neutralino as lightest superparticle (LSP) are excluded. A consistent picture is obtained with the gravitino as LSP, followed by a higgsino-like neutralino (NSP). Gravitinos with masses from 10 to 100 GeV may b...
متن کاملEmergent Dark Matter, Baryon, and Lepton Numbers
We present a new mechanism for transferring a pre-existing lepton or baryon asymmetry to a dark matter asymmetry that relies on mass mixing which is dynamically induced in the early universe. Such mixing can succeed with only generic scales and operators and can give rise to distinctive relationships between the asymmetries in the two sectors. The mixing eliminates the need for the type of addi...
متن کاملTheories relating baryon asymmetry and dark matter
*Correspondence: Stefano Morisi, Institut für Theoretische Physik und Astrophysik, Universität Würzburg, Campus Hubland North, Emil-Hilb-Weg 22, 97074 Würzburg, Germany e-mail: [email protected] The nature of dark matter and the origin of the baryon asymmetry are two of the deepest mysteries of modern particle physics. In the absence of hints regarding a possible solution to these myster...
متن کاملBaryon Asymmetry, Dark Matter and Quantum Chromodynamics
We propose a new scenario to explain the observed cosmological asymmetry between matter and antimatter, based on nonperturbative physics at the QCD scale. Our scenario relies on a mechanism of separation of matter and antimatter which would be in two different phases: conventional hadronic phase and novel, color superconducting phase. We argue that chunks of quarks or antiquarks in condensed co...
