In physics, force carrier is a particle whose creation, annihilation, and exchange gives rise to one of the forces of the universe. [1] It is believed that the force carriers, like the leptons and quarks, are fundamental particles with no substructure. The term force carrier is synonymous with field particle, messenger particle, and force mediator.
