- Ultraviolet_fixed_point abstract "In a quantum field theory, one may calculate an effectiveor running coupling constant that defines thecoupling of the theory measured at a given momentum scale.One example of such a coupling constantis the electric charge. Inapproximate calculations in severalquantum field theories, notably quantum electrodynamicsand theories of the Higgs particle, the running couplingappears to become infinite at a finite momentum scale.This issometimes called the Landau pole problem. It is notknown whether the appearance of these inconsistencies isan artifact of the approximation, or a real fundamentalproblem in the theory. However, the problem can be avoidedif an ultraviolet or UV fixed point appears in the theory.A quantum field theory has a UV fixed point if its renormalization group flow approaches a fixed point in the ultraviolet (i.e. short length scale/large energy) limit. This is related to zeroes of the beta-function appearing in the Callan-Symanzik equation.The large length scale/small energy limit counterpart is the infrared fixed point.".
