Resumen:
The observation of ultrahigh energy (UHE) neutrinos has become a
priority in experimental astroparticle physics. UHE neutrinos can be
detected with a variety of techniques. In particular, neutrinos can
interact in the atmosphere (downward-going neutrinos) or in the Earth
crust (Earth-skimming neutrinos), producing air showers that can be
observed with arrays of detectors at the ground. With the Surface
Detector Array of the Pierre Auger Observatory we can detect these types
of cascades. The distinguishing signature for neutrino events is the
presence of very inclined showers produced close to the ground (i.e.
after having traversed a large amount of atmosphere). In this work we
review the procedure and criteria established to search for UHE
neutrinos in the data collected with the ground array of the Pierre
Auger Observatory. This includes Earth-skimming as well as
downward-going neutrinos. No neutrino candidates have been found, which
allows us to place competitive limits to the diffuse flux of UHE
neutrinos in the EeV range and above.
