The highest energy cosmic rays from superheavy dark matter particles
E. V. Arbuzova
It is commonly accepted that high energy cosmic rays up to eV can be produced in catastrophic astrophysical processes. However the source of a few observed events with hi…
Cosmic rays from annihilation of heavy dark matter particles
E. V. Arbuzova, A. D. Dolgov, A. A. Nikitenko
The origin of the ultra high energy cosmic rays via annihilation of heavy stable, fermions "f", of the cosmological dark matter (DM) is studied. The particles in question are suppo…
Superheavy SUSY-kind dark matter and high energy cosmic rays
E. V. Arbuzova
The search for supersymmetric partners at Large Hadron Collider revealed negative result. Though, strictly speaking, it does not exclude low energy supersymmetry, but still it lead…
Cosmic rays from heavy particle decays
E. V. Arbuzova, A. D. Dolgov, A. A. Nikitenko
Multidimensional modification of gravity with a smaller mass scale of the gravitational interaction is considered. Stable by assumption dark matter particles could decay via intera…
Superheavy dark matter in cosmology with conformal anomaly
E. V. Arbuzova, A. D. Dolgov, R. S. Singh
Cosmological evolution and particle creation in -modified gravity are considered for the case of the dominant decay of the scalaron into a pair of gauge bosons due to conforma…
Problems of spontaneous and gravitational baryogenesis
E. V. Arbuzova, A. D. Dolgov
Spontaneous and closely related to it gravitational baryogenesis are critically analyzed. It is shown that the coupling of the curvature scalar to baryonic current, which induces n…
