Seminar : Searches for UHE neutrinos and upward-going showers at the Pierre Auger Observatory

Abstract:

The Pierre Auger Observatory plays a crucial role in detecting the most energetic particles in the Universe, including cosmic rays and neutrinos, to unravel their origins and contribute to multi-messenger astronomy. For the past two decades, during its Phase I, the Observatory has been actively searching for ultra-high-energy (UHE) neutrinos with energies above 0.1 EeV. These neutrinos can travel horizontally through the atmosphere or skim the Earth's crust, producing young air showers that can be detected by the Surface Detector Array, comprising 1,660 water-Cherenkov stations spread over an area of 3,000 km2. Searches have been conducted for both point sources and diffuse flux. Complementary to these efforts, the Auger Prime Radio Detector (RD) provides an independent and highly sensitive measurement of very inclined air showers, enabling additional neutrino searches. In addition, the Fluorescence Detector, consisting of 27 telescopes, has been used to search for upward-going air showers, motivated by the detection of ‘anomalous’ events by the ANITA instrument. These analyses also serve as a Testbed for up-going shower scenarios that may require physics beyond the Standard Model (BSM). In this presentation, the results of these searches and their astrophysical implications will be summarized, and the potential of the radio antennas will be highlighted.
