The Large Hadron Collider (LHC), the world's most powerful particle accelerator, is entering a major upgrade phase. CERN researchers hope that the new version of the accelerator will allow the discovery of previously unknown particles and test fundamental theories about the Universe with unprecedented precision. The project, called the High-Luminosity LHC (HL-LHC), represents one of the most important investments in modern physics and could pave the way for the next generation of particle
