The Atlas Experiment is a major scientific project conducted at the Large Hadron Collider (LHC) at CERN, designed to explore fundamental questions about particle physics. It focuses on detecting and analyzing particles produced from high-energy collisions of protons, helping scientists understand the basic building blocks of matter and the forces that govern their interactions. One of the key achievements of the Atlas Experiment was the discovery of the Higgs boson in 2012, a particle that gives mass to other particles through the Higgs field. This discovery confirmed a crucial aspect of the Standard Model of particle physics, enhancing our understanding of the universe's structure and origins.
