Neutrino, Cosmos, and New Physics
A. D. Dolgov
Observational manifestations of possible breaking of spin-statistics relation for neutrinos are considered. It is argued that bosonic neutrinos may form cosmological cold dark matt…
Big Bang and Heavy Particles
A. D. Dolgov
A possibility of existence of ultra-heavy (quasi)stable particles, mechanisms leading to their large life-time, their production in the early universe, and cosmological manifestati…
Suppressed neutrino oscillations and large lepton asymmetries
A. D. Dolgov, Fuminobu Takahashi
It is shown that hypothetical neutrino-majoron coupling can suppress neutrino flavor oscillations in the early universe, in contrast to the usual weak interaction case. This reopen…
Oscillations of neutrinos produced by a beam of electrons
A. D. Dolgov, L. B. Okun, M. V. Rotaev +1
We analyze a thought neutrino oscillation experiment in which neutrinos are produced by electrons colliding with atomic nuclei of a target. The neutrinos are detected by observing…
Problems of vacuum energy and dark energy
A. D. Dolgov
A simple description of the vacuum energy (cosmological constant) problem for non-experts is presented. Basic features of cosmology with non-zero vacuum energy are discussed. The a…
Cosmological Matter-Antimatter Asymmetry and Antimatter in the Universe
A. D. Dolgov
Models of baryogenesis which may lead to astronomically significant amount of antimatter in the universe are reviewed. Observational features are briefly discussed.
