Detection of inclined and horizontal showers in the Pierre Auger Observatory
نویسنده
چکیده
Abstract. The Pierre Auger Observatory can detect with high efficiency the air showers induced by ultra-high energy cosmic rays incident at large zenith angles θ > 60. We describe here the specific characteristics of inclined and horizontal showers, as well as the characteristics of their signal in the surface detector. We point out their relevance both to extend the potential of the detector, and in the context of the detection of high-energy cosmic neutrinos.

The sensitivity of the surface detector of the Pierre Auger Observatory to UHE Earth-skimming and down-going neutrinos
The Pierre Auger Observatory is sensitive to ultra-high energy neutrinos in the EeV range and above. In this work we describe the complete chain needed to compute the neutrino acceptance of the surface detector. We firstly address the computation of the probability that an ultra-high energy neutrino produces an air shower. Subsequently we present the simulations to deduce the detector response ...
متن کاملResponse of the Pierre Auger Observatory Water Cherenkov Detectors to Muons
Two test detectors similar to the Pierre Auger Observatory Water Cherenkov Detectors have been installed at the Observatory site and at the Institut de Physique Nucléaire d’Orsay. The signals from the tanks are read out using three 9” photomultipliers and analyzed by both a digital oscilloscope with high sampling frequency and the Auger surface detector electronics. Additionally, the detectors ...
متن کاملUltrahigh Energy Neutrinos at the Pierre Auger Observatory
The observation of ultrahigh energy neutrinos (UHEνs) has become a priority in experimental astroparticle physics. UHEνs can be detected with a variety of techniques. In particular, neutrinos can interact in the atmosphere (downward-going ν) or in the Earth crust (Earth-skimming ν), producing air showers that can be observed with arrays of detectors at the ground. With the Surface Detector Arra...
متن کاملSensitivity of the Auger Observatory to ultra high energy photon composition through inclined showers
We report a calculation of the expected rate of inclined air showers induced by ultra high energy cosmic rays to be obtained by the Auger Southern Observatory assuming different mass compositions. We describe some features that can be used to distinguish photons at energies as high as 10 20 eV. The discrimination of photons at such energies will help to test some models of the origin of ultra-h...
متن کاملMeasurements of the Muon Content of UHECR Air Showers with the Pierre Auger Observatory
The Pierre Auger Observatory, recently completed, has been operational since 2004. As a hybrid experiment, it allows for a wide range of measurements of UHECR-induced extensive air showers (EAS), including measurements of the EAS particle content on ground which is sensitive to high-energy hadronic interactions. We present the results of several independent measurements of the EAS muon content ...
