On 23 March an ALICE masterclass was held at CERN. Twenty students form the Collège Sismondi in Geneva participated in it. The event was a part of the annually-held international masterclasses, which this year took place in the period between 11 February and 23 March. They are organised by the International Particle Physics Outreach Group (IPPOG). This year 20 ALICE masterclasses were held in 13 countries, including South Africa, the USA, Brazil and Mexico. 

Gaëtan, one of the students participating in the masterclass, shared his impression of the exercises: “It was very interesting and I think the level was very good for us. It was not like going in a museum or like reading an article about physics. We could do an actual physics analysis. In the same time it was not too hard, because there were not too many maths concepts. We also learned new things, like for example what antimatter is. I really liked the fact that our questions were answered by real scientists.”

IPPOG is an international network of physicists, science communicators and educators. The International masterclasses are its flagship activity. Through them students from all over the world are given the chance to become particle physicists for a day by analysing real data from the Large Hadron Collider. At the end of each masterclass students from different countries gather together in a live videoconference with CERN to discuss and compare their discoveries and to share what they have learned during the day.
