Possible explanation of primordial Li deficit
E. V. Arbuzova, A. D. Dolgov
A reduction mechanism of the theoretically predicted excessive abundance of Li via baryons evaporated by primordial black holes is suggested. It is shown that the fraction of $…
Rates of particle production in gravity and supersymmetry-kind dark matter
E. V. Arbuzova, A. D. Dolgov
Universe heating in -modified gravity is considered. The rates of particle production by the scalaron are calculated for different decay channels. Freezing of massive stable r…
Dark matter in cosmology
E. V. Arbuzova, A. D. Dolgov, R. S. Singh
Production of massive stable relics in -modified gravity is considered. It is shown that the cosmological evolution and kinetics of massive species differs significantly from…
General properties and kinetics of spontaneous baryogenesis
E. V. Arbuzova, A. D. Dolgov, V. A. Novikov
General features of spontaneous baryogenesis are studied. The relation between the time derivative of the (pseudo)goldstone field and the baryonic chemical potential is revisited.…
Kinetics of spontaneous baryogenesis in non-stationary background
Elena Arbuzova, Alexander Dolgov, Victor Novikov
Generation of the cosmological baryon asymmetry in frameworks of spontaneous baryogenesis is studied in detail. It is shown that the relation between baryonic chemical potential an…
Modified gravity. Problems and observational manifestations
E. V. Arbuzova
Some models of modified gravity and their observational manifestations are considered. It is shown, that gravitating systems with mass density rising with time evolve to a singular…
Explosive phenomena in modified gravity
E. V. Arbuzova, A. D. Dolgov
Observational manifestations of some models of modified gravity, which have been suggested to explain the accelerated cosmological expansion, are analyzed for gravitating systems w…
