Observation of the GZK Cutoff Using the HiRes Detector
The High Resolution Fly’s Eye (HiRes) experiment has observed the GZK cutoff. HiRes observes two features in the ultra-high energy cosmic ray (UHECR) flux spectrum: the Ankle at an energy of 4 × 10 eV and a high energy suppression at 6×10 eV. The later feature is at exactly the right energy for the GZK cutoff according to the E1/2 criterion. HiRes cannot claim to observe a third feature at lowe...
متن کاملObservation of the GZK Cutoff by the HiRes Experiment
The High Resolution Fly’s Eye (HiRes) experiment has observed the GZK cutoff. HiRes’ measurement of the flux of cosmic rays shows a sharp suppression at an energy of 6×10 eV, exactly the expected cutoff energy. We observe the “ankle” of the cosmic ray spectrum as well, at an energy of 4× 10 eV. However we cannot claim to observe the third spectral feature of the ultrahigh energy cosmic ray regi...

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Evading the GZK Cosmic–Ray Cutoff
Explanations of the origin of ultra-high energy cosmic rays are severely constrained by the Greisen-Zatsepin-Kuz’min effect, which limits their propagation over cosmological distances. We argue that possible departures from strict Lorentz invariance, too small to have been detected otherwise, can affect elementary-particle kinematics so as to suppress or forbid inelastic collisions of cosmic-ra...
