In physics, the Landau pole (or the Moscow zero, or the Landau ghost) is the momentum (or energy) scale at which the coupling constant (interaction strength)...

Standard Model is not asymptotically free. So a Landau pole exists in the Standard Model. With the Landau pole a problem arises when Higgs boson is being considered...

perturbatively defined strong coupling constant diverges. This is known as the Landau pole. The confinement scale definition and value therefore depend on the renormalization...

ill-defined. In 4 dimensions, ϕ 4 {\displaystyle \phi ^{4}} theories have a Landau pole. This means that without a cut-off on the high-energy scale, renormalization...

this theory leads to problems. The Landau pole is sometimes referred as the Landau ghost. Named after Lev Landau, this ghost is an inconsistency in the...

coupling apparently becomes infinite at some finite energy, resulting in a Landau pole. However, one cannot expect the perturbative beta function to give accurate...

The coupling constant runs to infinity at finite energy, signalling a Landau pole. The problem is essentially that QED appears to suffer from quantum triviality...

infinitely strong at short enough distance scales. This property called a Landau pole, made it plausible that quantum field theories were all inconsistent...

persisted at large couplings, this would indicate the presence of a Landau pole at finite energy, arising from quantum triviality. However, the question...
