A model is proposed for the origin of cosmic rays (CRs) from ∼ 10 14 eV/nucleon to the highest energies ( > ∼ 10 20 eV). GRBs are assumed to inject CR protons and ions into the interstellar medium of star-forming galaxies-including the Milky Waywith a power-law spectrum extending to a maximum energy ∼ 10 20 eV. The CR spectrum near the knee is fit with CRs trapped in the Galactic halo that were accelerated and injected by an earlier Galactic GRB. These CRs diffuse in the disk and halo of the Galaxy due to gyroresonant pitch-angle scattering with MHD turbulence in the Galaxy's magnetic field. The preliminary (2001) KASCADE data through the knee of the CR spectrum are fit by a model with energy-dependent propagation of CR ions from a single Galactic GRB. Ultra-high energy CRs (UHECRs), with energies above the ankle energy at > ∼ 3 × 10 18 eV, are assumed to propagate rectilinearly with their spectrum modified by photo-pion, photo-pair, and expansion losses. We fit the measured UHECR spectrum assuming comoving luminosity densities of GRB sources consistent with possible star formation rate histories of the universe.For power-law CR proton injection spectra with injection number index p > ∼ 2 and low and high-energy cutoffs, normalization to the local time-and space-averaged GRB luminosity density implies that if this model is correct, the nonthermal content in GRB blast waves is hadronically dominated by a factor ≈ 60-200, limited in its upper value by energetic and spectral considerations. Calculations show that 100 TeV -100 PeV neutrinos could be detected several times per year from all GRBs with kilometer-scale neutrino detectors such as IceCube, for GRB blast-wave Doppler factors δ < ∼ 200. GLAST measurements of γ-ray components and cutoffs will constrain the product of the nonthermal baryon loading and radiative efficiency, limit the Doppler factor, and test this scenario.

“…In this model UHECRs are understood as the decay products of a resonant annihilation process of high energetic neutrinos with the relic neutrino background [19]. Since the neutrino mass scale is related to the UHECR energy and relic neutrino clustering on galactic scales may turn out to be a necessary ingredient of the model, an absolute neutrinos mass scale of ∼ 0.1 − 1 eV is predicted in this context [19,20]. In degenerate schemes the mass differences are not significant.…”

“…While this option of cold-hot-dark-matter cosmology has been disfavored by models including a cosmological constant, as supported by the supernova cosmology project, a new motivation for degenerate models with a less large mass scale may come from the Z-burst interpretation of ultra high energy cosmic rays (UHECRs). In this model UHECRs are understood as the decay products of a resonant annihilation process of high energetic neutrinos with the relic neutrino background [19]. Since the neutrino mass scale is related to the UHECR energy and relic neutrino clustering on galactic scales may turn out to be a necessary ingredient of the model, an absolute neutrinos mass scale of ∼ 0.1 − 1 eV is predicted in this context [19,20].…”

Abstract. We discuss the possibility of reconstructing the neutrino mass spectrum from the complementary processes of neutrino oscillations and double beta decay in view of the new data of Super-Kamiokande presented at the Neutrino2000 conference. Since the large mixing angle solution is favored, now, the prospects to observe double beta decay and provide informations on the absolute mass scale in the neutrino sector have been improved. Double Beta decay and neutrino oscillationsNeutrinos finally have been proven to be massive by atmospheric and solar neutrino oscillation experiments. However, the absolute scale of neutrino masses, a necessary ingredient for reconstructing beyond the standard model physics, is still unknown, since informations obtained in neutrino oscillation experiments regard the mass squared differences and mixing angles, only. Only both neutrino oscillations and neutrinoless double beta decay together could solve this absolute neutrino mass problem [1,2,3]. In this paper we discuss the most recent data , as presented by the Super-Kamiokande Collaboration at the Neutrino2000 conference [4]. The small mixing angle solution for solar neutrinos is ruled out, now, at 90 % C.L. Moreover, solutions including sterile neutrinos seemed to be disfavored both for atmospheric as well as for solar neutrinos. In the following we thus will restrict ourselves to a three neutrino framework, omitting the LSND anomaly. (For a discussion of the small mixing angle solution and four neutrino scenarios see [1]). A global analysis in a three neutrino framework yield the following favored regions [5,6]:• Solar neutrino oscillations favor ν e − ν e oscillations within the large mixing angle (LMA) MSW solution: ∆m 2 ⊙ = 3 (1 − 10) · 10 −5 eV 2 tan 2 θ ⊙ = 0.5 (0.2 − 0.6), where the bestfit is given with the 90 % C.L. region in the brackets.

“…At high energies, the Z resonance in the s channel for the process νν → X enhances the probability for the interaction of an UHEν with the CνB [3,4,5,6,7,8]). This process has also been proposed as a possible mechanism for generating UHE cosmic rays through the hadronic decay of the Z boson ("Z-burst" mechanism [9,10,11,12,13]). In that context, it has been pointed out that some features of the CνB (in particular the relic neutrino masses, energy spectra and densities) might be indirectly inferred from the observed spectrum of UHE cosmic rays [14,15].…”

We present a calculation of the damping of an ultra-energetic cosmic neutrino (UHEν) travelling through the thermal gas of relic neutrinos, using the formalism of finite-temperature field theory. From the self-energy diagram due to Z exchange, we obtain the annihilation cross section for an UHEν interacting with an antineutrino from the background. This method allows us to derive the full expression for the UHEν transmission probability, taking into account the momentum of relic neutrinos. We discuss the effect of thermal motion on the shape of the absorption dips for different UHEν fluxes as well as in the context of relic neutrino clustering. We find that for ratios of the neutrino mass to the relic background temperature 10 2 or smaller, the thermal broadening of the absorption lines could significantly affect the determination of the neutrino mass and of the characteristics of the population of UHEν sources.
