Coupling constant

In physics, a coupling constant or gauge coupling parameter (or, more simply, a coupling) is a number that determines the strength of the force exerted in an interaction. Originally, the coupling constant related the force acting between two static bodies to the "charges" of the bodies (i.e. the electric charge for electrostatic and the mass for…
