Identifying Particles (T. Wyatt et al, Manchester)

The purpose of these web pages is to allow you to identify for yourself some interesting particle physics interactions or "events". These events have been seen using an experiment called OPAL, at CERN, near to Geneva. The experiment ran from 1989 to 2000 at the Large Electron-Positron collider (LEP), which was installed in the largest particle accelerator tunnel of the world.
The emphasis is very much on your active participation. At the beginning You learn a few important things, which you need to know about the experiment and the different types of events that can occur. But the main parts are, where you play the role of a "particle detective" and identify for yourself pictures of different types of events.
