Experimental particle physicists are the explorers of the modern age - forever probing new territory, where no one has ever gone before. Using enormous particle accelerators buried deep beneath the surface of the earth, they unravel the world of elementary particles and peruse fundamental secrets of the universe. In this particle-experiment you'll learn how various particle detectors work, how can we say we "saw" a particle and measured its properties. Equipped with that you'll turn to recent real ATLAS data and will hunt for one of nature's most interesting elementary particle.
