The MSM, Inflation, and Dark Matter
Mikhail Shaposhnikov, Igor Tkachev
We show how to enlarge the MSM (the minimal extension of the standard model by three right-handed neutrinos) to incorporate inflation and provide a common source for electroweak…
Photons as Ultra High Energy Cosmic Rays ?
O. E. Kalashev, V. A. Kuzmin, D. V. Semikoz +1
We study spectra of the Ultra High Energy Cosmic Rays assuming primaries are protons and photons, and that their sources are extragalactic. We assume power low for the injection sp…
Matter Creation via Vacuum Fluctuations in the Early Universe and Observed Ultra-High Energy Cosmic Ray Events
V. A. Kuzmin, I. I. Tkachev
Cosmic rays of the highest energy, above the Greisen-Zatsepin-Kuzmin cut-off of the spectrum, may originate in decays of superheavy long-living X-particles. These particles may be…
Ultra-High Energy Cosmic Rays, Superheavy Long-Living Particles, and Matter Creation after Inflation
V. A. Kuzmin, I. I. Tkachev
The highest energy cosmic rays, above the Greisen-Zatsepin-Kuzmin cut-off of cosmic ray spectrum, may be produced in decays of superheavy long-living X-particles. We conjecture tha…
Microwave background anisotropy in low- inflationary models and the scale of homogeneity in the Universe
A. Kashlinsky, I. I. Tkachev, J. Frieman
We study the microwave background anisotropy due to superhorizon-size perturbations (the Grischuk-Zel'dovich effect) in open universes with negative spatial curvature. Using COBE r…
