Pierre Auger Observatory tests particle knowledge beyond reach of LHC
Scientists at the Pierre Auger Observatory recently tested the theory that governs the behavior of protons at energies inaccessible at the Large Hadron Collider.
In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC wraps up its 2025 lead-ion run, physicists recall how they worked together to solve the puzzle.
