Multiplicative BRST renormalization of the SU(2) Higgs model.
We reformulate the proof of the renormalization of a spontaneously broken gauge theory by multiplicatively renormalizing the vacuum expectation value of the Higgs field in the SU(2) Higgs model. After BRST symmetry was discovered [1], it was noted that the renormalization of gauge theories [2] can be simplified by using BRST methods. In [3] Becchi, Rouet and Stora considered the SU(2) Higgs mod...
متن کامل0 Renormalization of Non - locally Regularized BRST - anti - BRST theories
An extension of the non-local regularization scheme is formulated in the Sp(2) symmetric Lagrangian BRST quantization framework. It generates a systematic treatment of the anomalous quantum master equations and allows to subtract the divergences as well as to calculate genuine higher loop BRST and anti BRST anomalies.
متن کاملRenormalization Group Flow in BRST Invariant Open String σ-Model
The renormalization group flow in the theory space of a BRST invariant string σ-model is investigated. For the open bosonic string the non-perturbative off-shell effective action and its gauge symmetry properties are determined from β-functions defined by the local Weyl anomaly. The interactions are shown to explicitly break the free theory BRST invariance generating new non-linear gauge symmet...
متن کاملRenormalization-group-improved Higgs sector of the minimal supersymmetric model.
In the minimal supersymmetric model (MSSM) all Higgs self-coupling parameters are related to gauge couplings at tree-level. Leading-logarithmic radiative corrections to these quantities can be summed using renormalization group techniques. By this procedure we obtain complete leading-log radiative corrections to the Higgs masses, the CP-even Higgs mixing angle, and trilinear Higgs couplings. Ad...
متن کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
