Perhaps the simplest types of events to identify are those in which the
electron and positron annihilate to produce a Z0
that then decays to
produce a particle-antiparticle pair.
The particle and antiparticle then fly off back to back and are observed in
We represent the production of, for example, a muon-antimuon pair in
Z0 decay by means of the following diagram:
Here are some events containing the different types of particle-antiparticle pairs, with hints on how to identify them:
Once you've understood the way we identify the different
types of events, then please:
