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…
Cosmological Magnetic Fields and CMBR Polarization
A. D. Dolgov
A simple introduction to physics of CMBR polarization and the Faraday rotation of the latter in cosmic magnetic field is presented. The content of the lecture is the following: 1.…
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…
