LIMITS ON TOPOLOGICAL DEFECT NEUTRINO FLUXES FROM HORIZONTAL AIR SHOWER MEASUREMENTS

We obtain the horizontal air shower rate from the (EeV) high energy ne utrino flux predicted in some topological defect scenarios as the sour ce for the highest energy cosmic rays. Emphasis is made on the differe nt character of the events depending on the neutrino flavor and type o f interaction. We show that the bound for muon poor showers in the 10( 5)-10(7) GeV energy range is violated by maximal predictions for super conducting cosmic string neutrino fluxes, we compare it to other neutr ino flux limits, and we discuss the future of such measurements to fur ther constrain these models.
