Perturbation Constraint on Particle Masses in the Weinberg-Salam Model with Two Massless Higgs Doublets

概要
- 論文の詳細を見る
The Weinberg-Salam model with two Higgs doublets is investigated. The spontaneous breakdown of the gauge symmetry is assumed to be produced by the Coleman-Weinberg mechanism, keeping gauge hierarchies in grand unified theories in mind. A discrete symmetry is introduced to secure flavor-diagonal Yukawa interactions of neutral Higgs bosons and the absence of the axion. Bounds on various masses are obtained by imposing coupling constants to lie in a finite range for the validity of the perturbation theory. It will be found that there must be at least one Higgs boson whose mass is lighter than 40GeV, in order to satisfy the perturbation constraint at the unification mass scale in grand unified theories.
