Neutrinos from the Annihilation or Decay of Superheavy Relic Dark Matter Particles

چکیده
In light of the mounting evidence that the highest energy cosmic rays are dominated by protons and not gammarays, we discuss the prospect that these cosmic rays are generated in the decay or annihilation of superheavy relic particles. We calculate the high energy neutrino spectrum which results and normalize our results to the ultrahigh energy cosmic ray spectrum. We show that most scenerios are already constrained by present limits placed by the AMANDA experiment.

High Energy Neutrinos From Superheavy Dark Matter Annihilation
(Dated: August 2000) Abstract Superheavy (M > 10 GeV) particles produced during inflation may be the dark matter, independent of their interaction strength. Strongly interacting superheavy particles will be captured by the sun, and their annihilation in the center of the sun will produce a flux of energetic neutrinos that should be detectable by neutrino telescopes. Depending on the particle ma...
متن کاملUnstable superheavy relic particles as a source of neutrinos responsible for ultrahigh-energy cosmic rays
Decays of superheavy relic particles may produce extremely energetic neutrinos. Their annihilations on the relic neutrinos can be the origin of the cosmic rays with energies beyond the Greisen-Zatsepin-Kuzmin cutoff. The redshift acts as a cosmological filter selecting the sources at some particular value z(e)+/-deltaz, for which the present neutrino energy is close to the Z pole of the annihil...
متن کاملDirect and Indirect Search for Dark Matter
Direct and indirect searches for dark matter (DM) particles are discussed. The search for a diffuse signal from DM annihilation in the Milky Way is presented using the atmospheric neutrino data from Super-Kamiokande-I, -II, -III. The analysis focuses on the model independent scenario with DM particles annihilating directly into pairs of neutrinos and antineutrinos. No signal contribution is all...
متن کاملOn heavy Majorana neutrinos as a source of the highest energy cosmic rays
Cosmic ray events beyond the Greisen-Zatsepin-Kuzmin cutoff represent a great challenge for particle physics and cosmology. We show that the physics of heavy Majorana neutrinos, well defined by their masses, cross sections and lifetimes, could explain the highest energy cosmic rays as a consequence of the galactic annihilation of heavy neutrinos as cold dark matter particles. Galactic nuclei ac...
متن کاملUltra-high energy cosmic rays from annihilation of superheavy dark matter
We consider the possibility that ultra-high energy cosmic rays originate from the annihilation of relic superheavy darkmatter.We find that a cross section of 〈σAv〉 ∼ 10cm(MX/10 GeV)3/2 is required to account for the observed rate of super-GZK events if the superheavy dark matter follows a Navarro–Frenk–White density profile. This would require extremely large-l contributions to the annihilation...
