The CMS experiment is one of the big detector at the largest particle physics accelerator in the world, the Large Hadron Collider(LHC) at CERN. More than 5000 physicists, engineers, computer scientists, technicians, administrative personnel, and students from over 50 countries across the globe work together to advance scientific knowledge, making CMS one of the largest scientific collaborations in the world. Founded in 1992, CMS is one of the two experiments at the #LHC that announced the discovery of the Higgs boson in 2012, opening a new chapter in particle physics. The CMS detector acts as a giant high-speed camera, taking “3D photographs” of the subatomic particles’ collisions, leading to a better understanding of the structure of matter and of the forces that rule the universe at the atomic scale.
