Effects of atmospheric electric fields on detection of ultrahigh-energy cosmic rays
Alexander Kusenko, Dmitry Semikoz
We show that atmospheric electric fields may affect the cosmic ray observations in several ways and may lead to an overestimation of the cosmic ray energies. The electric field in…
Bounds on heavy sterile neutrinos revisited
Alexander Kusenko, Silvia Pascoli, Dmitry Semikoz
We revise the bounds on heavy sterile neutrinos, especially in the case of their mixing with muon neutrinos in the charged current. We summarize the present experimental limits, an…
Gamma ray bursts and the origin of galactic positrons
Gianfranco Bertone, Alexander Kusenko, Sergio Palomares-Ruiz +2
A recent observation of the 511 keV electron-positron annihilation line from the Galactic bulge has prompted a debate on the origin of the galactic positrons responsible for this e…
Long and short gamma-ray bursts, and the pulsar kicks
Alexander Kusenko, Dmitry V. Semikoz
One of the mysteries that surround gamma-ray bursts (GRB) is the origin of two classes of events: long and short GRB. The short GRB are similar to the first second of a long GRB. W…
New hadrons as ultra-high energy cosmic rays
M. Kachelriess, D. V. Semikoz, M. A. Tortola
Ultra-high energy cosmic ray (UHECR) protons produced by uniformly distributed astrophysical sources contradict the energy spectrum measured by both the AGASA and HiRes experiments…
Lepton asymmetry creation in the Early Universe
R. Buras, D. V. Semikoz
Oscillations of active to sterile neutrinos with a small mixing angle sin 2 θ< 10^{-2} could generate a large lepton asymmetry in the Early Universe. The final order of magnitude o…
