Possible test for the suggestion that air showers with E > 10(20) eV are due to strongly interacting neutrinos

摘要

The suggestion is made that air showers with energies beyond the Greisen-Zatsepin-Kuz'min spectral cutoff may have primary vertices some 6 km lower in height than those of proton initiated showers with energies below the GZK cutoff. This estimate is based on the assumption that post-GZK showers are due to neutrinos having acquired strong interactions from generation-changing dual gluon exchange as recently proposed. © 1998 Elsevier Science B.V.
