Particle Interactions: A tale of tracks

With only one set of tracks, we must infer the passage of something known to leave those kinds of tracks

Two sets of tracks require an interaction: What happened here?

One possibility: not an especially conservative one…

Yummy!

Many types of interactions may be observed Here’s an important question: if all you saw were these tracks, how do you know which way this goes?

Some interactions leave no tracks. Is this just a detection problem Some interactions leave no tracks! Is this just a detection problem? Or some real property?

Conservation laws assure us that all interactions play by the established rules. back
