A renormalized interaction strength whose value depends on energy or length scale according to a beta function.
wp-physics-running_couplingnlab-physics-running_couplingpdg-qcdtong-qftEach relation below ends at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
A renormalized coupling generally depends on the chosen energy scale according to its beta function.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
wp-physics-coupling_constanttong-qftwp-physics-running_couplingnlab-physics-running_couplingpdg-qcdThis is an authored directed relation from the source endpoint to the target endpoint.
Running couplings solve renormalization-group flow equations.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
