Beta function of three-dimensional QED

Web4.1 The β-function The value of renormalized coupling constants are renormalization prescription dependent. In par-ticular, they depend on the value of the momentum µ, at which the innite Green functions are subtracted - in dimensional regularization this is the mass scale, µ, which controls the dimension-ful bare coupling outside four ... WebWe can see this from the QED beta-function. This tells us that the electric charge (which is the coupling parameter in the theory) increases with increasing energy. Therefore, while the quantized electromagnetic field without charged particles is scale-invariant, QED is not scale-invariant.
