Abstract

The hypothesis of topological defects (from grand unified and/or Planck scales) as the sources of extremely high-energy ({gt}10{sup 18}-eV) cosmic rays predicts an unusually high content of {gamma} rays at energies {ital E}{approx gt}10{sup 20} eV ({gamma}/{ital p}{gt}=1) and {ital E}{approx lt}10{sup 14} eV ({gamma}/{ital p}{approx gt}10{sup {minus}3}). This can be used as a signature for testing the hypothesis in forthcoming experiments.

Lorentz Violation for Photons and Ultrahigh-Energy Cosmic Rays

Journal Article Galaverni, Matteo; Sigl, Guenter - Physical Review Letters

Lorentz symmetry breaking at very high energies may lead to photon dispersion relations of the form {omega}{sup 2}=k{sup 2}+{xi}{sub n}k{sup 2}(k/M{sub Pl}){sup n} with new terms suppressed by a power n of the Planck mass M{sub Pl}. We show that first and second order terms of size |{xi}{sub 1}| > or approx. 10{sup -14} and {xi}{sub 2} < or approx -10{sup -6}, respectively, would lead to a photon component in cosmic rays above 10{sup 19} eV that should already have been detected, if corresponding terms for e{sup {+-}} are significantly smaller. This suggests that LI breaking suppressed up to secondmore »« less

Helium photodisintegration and nucleosynthesis: Implications for topological defects, high energy cosmic rays, and massive black holes

Journal Article Sigl, G; Jedamzik, K; Schramm, D; ... - Physical Review, D

We consider the production of {sup 3}He and {sup 2}H by {sup 4}He photodisintegration initiated by nonthermal energy releases during early cosmic epochs. We find that this process cannot be the predominant source of primordial {sup 2}H since it would result in anomalously high {sup 3}He/D ratios in conflict with standard chemical evolution assumptions. We apply this fact to constrain topological defect models of highest energy cosmic ray (HECR) production. Such models have been proposed as possible sources of ultrahigh energy particles and {gamma} rays with energies above 10{sup 20} eV. The constraints on these models derived from {sup 4}Hemore »« less

Connection between relic neutrinos and cosmic rays at [approx gt]10[sup 20]; eV

Conference Weiler, T - AIP Conference Proceedings

The observation of cosmic-ray events above the Greisen[endash]Kuzmin[endash]Zatsepin (GZK) cutoff of 5[times]10[sup 19] hthinsp;eV challenges orthodox modeling. We discuss a possible solution which uses Standard Model (SM) physics augmented only by [approx lt] eV neutrino masses as suggested by solar, atmospheric, and terrestrial neutrino detection and the cosmological preference for a hot dark matter component. In this scheme, cosmic ray neutrinos from distant, highest-energy sources annihilate relatively nearby on the relic-neutrino background to produce [open quotes]Z-bursts[close quotes], highly-collimated, highly-boosted ([gamma][sub Z][approximately]10[sup 11]) hadronic jets. iquest;From the SM and hot Big Bang cosmology, the probability for each neutrino flavor at itsmore »« less
Gamma ray bursts and extreme energy cosmic rays

Journal Article Scarsi, Livio - AIP Conference Proceedings

Extreme Energy Cosmic Ray particles (EECR) with E>10{sup 20} eV arriving on Earth with very low flux ({approx}1 particle/Km{sup 2}-1000yr) require for their investigation very large detecting areas, exceeding values of 1000 km{sup 2} sr. Projects with these dimensions are now being proposed: Ground Arrays ('Auger' with 2x3500 km{sup 2} sr) or exploiting the Earth Atmosphere as seen from space ('AIR WATCH' and OWL,'' with effective area reaching 1 million km{sup 2} sr). In this last case, by using as a target the 10{sup 13} tons of air viewed, also the high energy neutrino flux can be investigated conveniently. Gammamore »« less

''Quasidirect'' observations of cosmic-ray primaries in the energy region 10/sup 12/--10/sup 14/ eV

Journal Article Kawamura, Y; Matsutani, H; Nanjyo, H; ... - Phys. Rev. D; (United States)

We have exposed an emulsion chamber at a level of 32.8 g/cm/sup 2/ for /similar to/30 h, and detected /similar to/800 showers on x-ray films (Fuji No. 200 type). Among these, /similar to/200 primaries(/Sigma/ /ital E//sub /gamma///ge/2TeV, /theta//lt/75/degree/) were identified by tracing back through successive plates of nuclear emulsion.
