Each year about 4000 high school students in 20 countries come to one of about 70 nearby universities or research centres 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.

The central element of the EPPOG Masterclasses 2008 will be the International Masterclass weeks from 28.02.08 - 14.03.08, where each day up to seven out of about 70 institutes participate. In addition, separate Institute Masterclasses take place, distributed over the whole year.

This program is organized by the European Particle Physics Outreach Group EPPOG. The video linkup between the instututes is realized using the EVO technology, with valuable technical support from the Caltech EVO team (including the EVO Slovak group) and CERN. We acknowledge financial support from the EPS HEPP High-Energy and Particle Physics Division, the EPS PED Physics Education Division and the Slovak Ministry of Education. Printed material for the students is contributed from CERN and DESY. An offline version of this website is available as CD-ROM from the organizers and distributed to all participating students.
