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…
Do neutrino flavor oscillations forbid large lepton asymmetry of the universe ?
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…
