coupling constant [′kəp·liŋ ′kän·stənt] (particle physics) A measure of the strength of a type of interaction between particles, such as the strong interaction between mesons and nucleons, and the weak interaction between four fermions; analogous to the electric charge, which is the coupling constant between charged particles and electromagnetic radiation. (physics) A measure of the strength of the coupling between two systems, especially electric circuits; maximum coupling is 1 and no coupling is 0. Also known as coefficient of coupling; coupling coefficient. A measure of the dependence of one physical quantity on another. How to thank TFD for its existence?

| Neutron [beta]-decay provides the most precise measurements of the relative axial-vector coupling constant [lambda]. Within the framework of the standard model, neutron decay can be used to determine the weak vector coupling constant [g. A] is the axial coupling constant, and the correlation coefficients a, A, B are incorporated into the recoil corrections [C. |
