    Search for patterns by combining cosmic-ray energy and arrival directions at the Pierre Auger Observatory

    Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with ...

    Measurement of negatively charged pion spectra in inelastic p+p interactions at \(p_{\mathbf {lab}}= \) 20, 31, 40, 80 and 158 GeV/c

    We present experimental results on inclusive spectra and mean multiplicities of negatively charged pions produced in inelastic p+p interactions at incident projectile momenta of 20, 31, 40, 80 and 158 GeV/c ( ...
