Abstract This White Paper presents an overview of the current status and future perspective
of QCD research, based on the community inputs and scientific conclusions from the 2022 …

We test the hypothesis of starburst galaxies as sources of ultrahigh energy cosmic rays and
high energy neutrinos. The computation of interactions of ultrahigh energy cosmic rays in the …

Abstract The Telescope Array Collaboration recently reported the detection of a cosmic-ray
particle," Amaterasu," with an extremely high energy of 2.4× 10 20 eV. Here we investigate …

Galaxy clusters are the largest objects in the Universe kept together by gravity. Most of their
baryonic content is made of a magnetized diffuse plasma. We investigate the impact of such …

Soon, a new generation of neutrino telescopes, presently under planning, will target the
discovery of ultra-high-energy (UHE) neutrinos of cosmic origin, with energies higher than …

In turbulent magnetized plasmas, charged particles can be accelerated to high energies
through their interactions with the turbulent motions. As they do so, they draw energy from …

A dipole anisotropy in ultra–high-energy cosmic ray (UHECR) arrival directions, of
extragalactic origin, is now firmly established at energies E> 8 EeV. Furthermore, the …

The combined fit of the measured energy spectrum and shower maximum depth
distributions of ultra-high-energy cosmic rays is known to constrain the parameters of …

Abstract Recently the Telescope Array collaboration reported an observation of cosmic ray
event with very high energy 244 EeV (2.44× 10 20 eV). Importantly, the event is hard to …

Context. Jets of active galactic nuclei are potential accelerators of ultra high-energy cosmic
rays. Supernovae can occur inside these jets and contribute to cosmic ray acceleration …
