Observation of the Moon and Sun shadows with cosmic rays at an average energy of eV
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +346
Interactions of cosmic rays with the Moon and the Sun produce deficits in their arrival-direction distributions relative to an isotropic flux. Such shadows have been observed previ…
Search for active-sterile neutrino transitions using Pierre Auger Observatory data
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +348
We investigate the sensitivity of the Pierre Auger Observatory to physics beyond the Standard Model arising from magnetic-moment-induced transitions between active and heavy steril…
Proton-air interaction properties at TeV from shower-depth measurements with the Pierre Auger Observatory and their connection to the Muon Puzzle
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +347
Hybrid measurements at the Pierre Auger Observatory indicate that most high-energy hadronic interaction models underestimate the average depth of the shower maximum, $\langle X_{\m…
Forward hadron production in proton-air collisions above LHC energies through the fluctuations of extensive air showers
Lorenzo Cazon, Ruben Conceição, Miguel Alexandre Martins +1
Primary proton-air interactions at ultra-high energies leave a physically interpretable imprint on the correlated fluctuations of the depth of shower maximum and the muon content i…
Measuring the muon content of inclined air showers using AERA and the water-Cherenkov detectors of the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +360
We present a novel approach for assessing the muon content of air showers with large zenith angles on a combined analysis of their radio emission and particle footprint. We use the…
Scaler data from the Pierre Auger Observatory as a proxy of solar activity
C. Taricco, I. Bizzarri, C. Dionese +1
Solar activity variations strongly impact the modulation of the flux of low-energy Galactic Cosmic Rays (GCRs) reaching the Earth. The secondary particles, which originate from the…
