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…
Constraints on metastable superheavy dark matter coupled to sterile neutrinos with the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +368
Dark matter particles could be superheavy, provided their lifetime is much longer than the age of the universe. Using the sensitivity of the Pierre Auger Observatory to ultra-high…
Azimuthal fluctuations and number of muons at the ground in muon-depleted proton air showers at PeV energies
A. Bakalová, R. Conceição, L. Gibilisco +4
Muon counting is an effective strategy for discriminating between gamma and hadron-initiated air showers. However, their detection, which requires shielded detectors, is highly exp…
Gamma/hadron discrimination at high energies through the azimuthal fluctuations of the particle distributions at ground
R. Conceição, L. Gibilisco, M. Pimenta +1
Wide field-of-view gamma-ray observatories must fight the overwhelming cosmic ray background to identify very-high-energy astrophysical gamma-ray events. This work introduces a nov…
: a new variable for discrimination in large gamma-ray ground arrays
R. Conceição, B. S. González, M. Pimenta +1
In this letter, a new strategy to enhance the discrimination of high energy gamma rays from the huge charged cosmic rays background in large cosmic rays ground arrays is presented.…
New methods to reconstruct and the energy of gamma-ray air showers with high accuracy in large wide-field observatories
R. Conceição, L. Peres, M. Pimenta +1
Novel methods to reconstruct the slant depth of the maximum of the longitudinal profile (\Xmax) of high-energy showers initiated by gamma-rays as well as their energy () are p…
