Journal ArticleDOI
Cosmic abundances of stable particles: Improved analysis
TL;DR: An exact relativistic single-integral formula for the thermal average of the annihilation cross section times velocity, the key quantity in the determination of the cosmic relic abundance of a species, is obtained in this paper.
Journal ArticleDOI
Left-Handed Neutrino Mass Scale and Spontaneously Broken Lepton Number
TL;DR: In this paper, the Weinberg-Salam model was extended to include neutrino masses in the most economical way and two new particles, a Goldstone boson and a neutral Higgs with low mass, appeared coupled strongly to neutrinos but so weakly to the other fermions that they cannot be detected at present laboratory energies.
Journal ArticleDOI
Correlation of the highest-energy cosmic rays with nearby extragalactic objects.

TL;DR: The energy spectrum of cosmic rays above 2.5 x 10;{18} eV, derived from 20,000 events recorded at the Pierre Auger Observatory, is described and the hypothesis of a single power law is rejected with a significance greater than 6 standard deviations.
Journal ArticleDOI
Compatibility of DAMA/LIBRA dark matter detection with other searches
TL;DR: In this paper, the authors examined the effect of channeling on the DAMA/NaI/DAMA/LIBRA energy spectrum of the combined DAMA modulation data, which may be interpreted as a signal for the existence of weakly interacting dark matter (WIMPs) in our galactic halo.
