Strongly interacting neutrinos as the highest energy cosmic rays
Z. Fodor, S. D. Katz, A. Ringwald +1
We show that all features of the ultrahigh energy cosmic ray spectrum from 10^{17} eV to 10^{21} eV can be described with a simple power-like injection spectrum of protons under th…
Z-Burst Scenario for the Highest Energy Cosmic Rays
Z. Fodor, S. D. Katz, A. Ringwald
The origin of highest energy cosmic rays is yet unknown. An appealing possibility is the so-called Z-burst scenario, in which a large fraction of these cosmic rays are decay produc…
Ultrahigh energy cosmic rays as a Grand Unification signal
Z. Fodor, S. D. Katz
We analyze the spectrum of the ultrahigh energy (above \approx 10^{9} GeV) cosmic rays. With a maximum likelihood analysis we show that the observed spectrum is consistent with the…
Propagation of ultrahigh energy cosmic rays and compact sources
Z. Fodor, S. D. Katz
The clustering of ultrahigh energy (>10^{20} eV) cosmic rays (UHECR) suggests that they might be emitted by compact sources. Statistical analysis (Dubovsky et al., 2000) estimated…
Possible detection of relic neutrinos and determination of their mass: quantitative analysis
Z. Fodor, S. D. Katz, A. Ringwald
We consider the possibility that a large fraction of the ultrahigh energy cosmic rays are decay products of Z bosons which were produced in the scattering of ultrahigh energy cosmi…
Astroparticle physics signals beyond the Standard Model
S. D. Katz
In this thesis two signals pointing beyond the Standard Model are discussed. The first signal is the presence of baryonic matter around us. The possibility of baryogenesis in the M…
