A bit of history and present status 1996: Started in UK 2005: Adopted by EPPOG (European Particle Physics Outreach Group) for all Europe Use data from LEP (the Large Electron Positron collider, CERN, 1989-2000) OPAL Identifying Particles DELPHI Hands on CERN Z0 decays / calculation of branching ratios 2006: U.S. joined program 2010: preparing to move to LHC-based Masterclasses 2011: Start using data from LHC (the Large Hadron Collider, CERN, 2009 -) ATLAS W+W- (MINERVA) structure of the proton ATLAS Z0 (HYPATIA) mass, width (+Z' from MC) CMS J/Ψ (in 2011) and W/Z (in 2012) ALICE Looking for strange particles (V0 and cascade decays) ALICE Nuclear modification factor LHCB Measurement of the D o lifetime TOTEM Central organisation TU Dresden (Uta Bilow, Michael Kobel) and Fermilab (Ken Cecire) 2 Puebla 28.10.2015

A day of immersion in particle physics for 16-18 year old pupils Typical day of International Masterclasses Morning : introductory lectures on Particle physics (elementary particles, forces, Standard Model and beyond) Detectors – accelerators – experimental methods Visit of laboratory / experimental site Lunch (and discussion with scientists and University students) Afternoon : pupils do physics measurement They work in groups of 2 per computer and analyze visually (in most cases) data from an LHC experiment Summing of results of many groups – Discussion of results At the end of the day : Video Conference moderated by two physicists at CERN and connecting up to 5 institutes which did the same measurement that day 4 Puebla 28.10.2015
