Finite Quantum Field Theory and Renormalization Group (2012.04487v2)
Published 2 Dec 2020 in physics.gen-ph, hep-ph, and hep-th
Abstract: Renormalization group methods are applied to a scalar field within a finite, nonlocal quantum field theory formulated perturbatively in Euclidean momentum space. It is demonstrated that the triviality problem in scalar field theory, the Higgs boson mass hierarchy problem and the stability of the vacuum do not arise as issues in the theory. The scalar Higgs field has no Landau pole.
