The ATLAS Collaboration is a global collaboration of physicists and engineers from 38 institutions in 15 countries, primarily involved in the design, construction, and operation of the ATLAS experiment at the Large Hadron Collider (LHC). The collaboration aims to study particle physics by analyzing data collected from the LHC, focusing on the properties and interactions of fundamental particles. The ATLAS experiment is one of the largest and most complex scientific projects in particle physics, with contributions from various universities, research institutes, and national laboratories around the world. The collaboration's work is crucial for advancing our understanding of the fundamental nature of matter and the universe.The ATLAS Collaboration is a global collaboration of physicists and engineers from 38 institutions in 15 countries, primarily involved in the design, construction, and operation of the ATLAS experiment at the Large Hadron Collider (LHC).
