ATLAS Z-path Masterclass

Each year more than 10.000 high school students in over 40 countries come to one of about 200 nearby universities or research centers for one day in order to unravel the mysteries of particle physics. Lectures from active scientists give insight in topics and methods of basic research at the fundaments of matter and forces, enabling the students to perform measurements on real data from particle physics experiments themselves. At the end of each day, like in an international research collaboration, the participants join in a video conference for discussion and combination of their results.

In the ATLAS Z-path masterclass, students identify events to build a histogram of the masses of Z bosons and other particles that show  decays into 2 leptons. They also identify 4-lepton and 2-photon events to build mass histograms from these as well.
