Regge theory

Regge theory is like a way of explaining how particles move and interact with each other. Imagine you have a bunch of toys like marbles and balls that can bounce off each other. These toys can move in different ways, some fast and some slow.

Regge theory is like saying that each toy has its own special way of moving and bouncing off other toys. We call these special ways of moving "trajectories." Think of it like each toy has its own track or path it follows when it moves around.

Now, if we put a lot of these toys together and they start bouncing off each other, we can watch how they move and see if they follow certain patterns. Scientists can use regge theory to predict these patterns and figure out how the toys are interacting with each other.

So, in a nutshell, regge theory helps scientists understand how particles move and interact with each other by predicting the paths or trajectories they follow.
