The Quasi-Infra-Red Fixed Point at Higher Loops
نویسندگان
چکیده
We calculate the four-loop β-function for the generalised Wess-Zumino model. We use the result and Padé-Borel summation to discuss the domain of attraction of the quasi-infra-red fixed point of the top-quark Yukawa coupling in the supersymmetric standard model, and argue that the domain is in fact substantial.

Quasi-infra-red fixed points and renormalisation group invariant trajectories for non-holomorphic soft supersymmetry breaking
In the MSSM the quasi-infra-red fixed point for the top-quark Yukawa coupling gives rise to specific predictions for the soft-breaking parameters. We discuss the extent to which these predictions are modified by the introduction of additional “non-holomorphic” soft-breaking terms. We also show that in a specific class of theories, there exists an RGinvariant trajectory for the “non-holomorphic”...
متن کاملRenormalization Group Evolution and Infra-red Fixed Points in Minimal Supersymmetric Standard Model with Baryon and Lepton Number Violation
We study the renormalization group evolution and infra-red stable fixed points of the Yukawa couplings and the soft supersymmetry breaking trilinear couplings of the minimal supersymmetric standard model with baryon and lepton number (and R-parity) violation involving the heaviest generations. We show analytically that in the Yukawa sector there is only one infra-red stable fixed point. This co...
متن کاملThe Quasi - Fixed MSSM
The infra-red fixed points are determined for all the parameters of the MSSM. They dominate the renormalisation group running when the top-Yukawa is in the quasi-fixed point regime (i.e. large at the GUT scale). We examine this behaviour analytically, by solving the full set of one-loop renormalisation group equations in the approximation that the electroweak contributions are negligible, and a...
متن کاملInfra-red fixed points in supersymmetry
The Standard Model (SM) is a great success in describing the strong and electroweak interactions based on an underlying gauge principle, but one of its main weaknesses is that the masses of the matter particles, the quarks and leptons, are free parameters of the theory. This weakness persists in the Minimal Supersymmetric Standard Model (MSSM). The fermions mass problem in the MSSM arises from ...
متن کاملInfra-red stable fixed points of R-parity violating Yukawa couplings in supersymmetric models
We investigate the infra-red stable fixed points of the Yukawa couplings in the minimal version of the supersymmetric standard model with R-parity violation. Retaining only the R-parity violating couplings of higher generations, we analytically study the solutions of the renormalization group equations of these couplings together with the topand b-quark Yukawa couplings. We show that only the B...
