Particle mixing as possible explanation of the dark energy conundrum
The vacuum condensate due to neutrino and quark mixing behaves as a perfect fluid and, at the present epoch, as a cosmological constant. The very small breaking of the Lorentz invariance constrains today the value of the dark energy.
متن کاملSedenion Dark Matter Energy in Vedic Particle Physics
Vedic Particle Physics posits 56 types of spaces in the atomic nucleus, 28 positive and 28 negative in terms of energy loss or gain. Energy is derived from functioning Dark Matter via structures which probably are isomorphic to Spinor Fields, called Sakti and Asakti in Sanskrit, and which relate directly to the Octonions and Sedenions.
متن کاملDark Matter and Dark Energy
I briefly review our current understanding of dark matter and dark energy. The first part of this paper focusses on issues pertaining to dark matter including observational evidence for its existence, current constraints and the ‘abundance of substructure’ and ‘cuspy core’ issues which arise in CDM. I also briefly describe MOND. The second part of this review focusses on dark energy. In this pa...
متن کاملDark Matter and Particle Physics
Astrophysicists now know that 80% of the matter in the universe is ‘dark matter’, composed of neutral and weakly interacting elementary particles that are not part of the Standard Model of particle physics. I will summarize the evidence for dark matter. I will explain why I expect dark matter particles to be produced at the CERN LHC. We will then need to characterize the new weakly interacting ...
متن کاملDark Energy and Neutrino Model in Susy – Remarks on Active and Sterile Neutrinos Mixing –
We consider a Mass Varying Neutrinos (MaVaNs) model in supersymmetric theory. The model includes effects of supersymmetry breaking transmitted by the gravitational interaction from the hidden sector, in which supersymmetry was broken, to the dark energy sector. Then evolutions of the neutrino mass and the equation of state parameter of the dark energy are presented in the model. It is remarked ...
