Cosmological implications of photon-flux upper limits at ultra-high energies in scenarios of Planckian-interacting massive particles for dark matter

The Pierre Auger Collaboration, P. Abreu, M. Aglietta +374

Using the data of the Pierre Auger Observatory, we report on a search for signatures that would be suggestive of super-heavy particles decaying in the Galactic halo. From the lack…

Investigating Hadronic Interactions at Ultra-High Energies with the Pierre Auger Observatory

Isabel Goos, :, P. Abreu +374

The development of an extensive air shower depends not only on the nature of the primary ultra-high-energy cosmic ray but also on the properties of the hadronic interactions. For e…

Limits to gauge coupling in the dark sector set by the non-observation of instanton-induced decay of Super-Heavy Dark Matter in the Pierre Auger Observatory data

The Pierre Auger Collaboration, P. Abreu, M. Aglietta +374

Instantons, which are non-perturbative solutions to Yang-Mills equations, provide a signal for the occurrence of quantum tunneling between distinct classes of vacua. They can give…

Testing effects of Lorentz invariance violation in the propagation of astroparticles with the Pierre Auger Observatory

The Pierre Auger Collaboration, P. Abreu, M. Aglietta +374

Lorentz invariance violation (LIV) is often described by dispersion relations of the form with delta different based on particle type , with…

Simulations of Fast Neutrino Flavor Conversions with Interactions in Inhomogeneous Media

Guenter Sigl

We investigate toy models for spatial and temporal instabilities in collective neutrino oscillations induced by neutrino self-interactions, with special emphasis on inhomogeneous s…

The energy spectrum of cosmic rays beyond the turn-down around eV as measured with the surface detector of the Pierre Auger Observatory

The Pierre Auger Collaboration, P. Abreu, M. Aglietta +374

We present a measurement of the cosmic-ray spectrum above 100\,PeV using the part of the surface detector of the Pierre Auger Observatory that has a spacing of 750~m. An inflection…
