Resumen:
Neutrinos with energies above 1017eV are detectable with the Surface Detec-tor Array of the Pierre Auger Observatory. The identification is efficiently performed forneutrinos of all flavors interacting in the atmosphere at large zenith angles, as well as forEarth-skimmingτneutrinos with nearly tangential trajectories relative to the Earth. Noneutrino candidates were found in∼14.7 years of data taken up to 31 August 2018. Thisleads to restrictive upper bounds on their flux. The 90% C.L. single-flavor limit to the diffuseflux of ultra-high-energy neutrinos with anE−2νspectrum in the energy range 1.0×1017eV?2.5×1019eV isE2dNν/dEν<4.4×10−9GeV cm−2s−1sr−1, placing strong constraints onseveral models of neutrino production at EeV energies and on the properties of the sourcesof ultra-high-energy cosmic rays.
