Practice task: Try it out!

In the following events the annihilation of one electron and one positron in the SuperKEKB produced one particle-antiparticle-pair.

Try to find out and understand what kind of events all of these are by following the event-identification-flowchart below. When in doubt, try looking again at the example events. To check your conclusion, simply click “event 1” – “12”. for a better resolution you can also look at all the practice tasks combined in one PDF.

After successfully identifying all practice events, you are ready to start the main task. Here, the number of color charges of the strong interaction, that can be carried by a quark, is measured experimentally by you.
