The International Particle Physics Outreach Group and QuarkNet
Every year, thousands of high-school students all over the world become particle physicists for a day, and visit nearby CMS institutes and universities to perform real analyses using public CMS data. The CMS Masterclass exercise is developed by QuarkNet and conducted under the aegis of the International Particle Physics Outreach Group.
