Abstract
A new scenario of the formation of observed ultrahigh-energy cosmic-ray electron/positron and nuclei spectra is discussed within a nonclassical (superdiffusion) model of particle propagation in highly inhomogeneous interstellar and intergalactic media. It is shown that the proposed scenario provides a consistent description of data from highly precise satellite measurements, ground-based hybrid EAS arrays, and Cherenkov telescopes using the spectra of leptons and nuclei, and the mass composition of cosmic rays in the super- and ultrahigh ranges of energy.
