Force Carriers

In particle processes the forces are described as due to the exchange of particles, called "force carriers"; for each type of force there is an associated carrier particle. They belong to the class of particles, called bosons.

Picture two players tossing a (heavy) basketball back and forth. If you were far enough away, you would not see the basketball but you would realize that there is something that accounts for the players' motion.


The basketball is similar to the carrier particle exchanged between two particles. The force carrier can be produced or absorbed only by particles that have "charges" for that interaction.
