Analytic evaluation of two–loop renormalization constants of enhanced electroweak strength in the Higgs sector of the Standard Model
نویسنده
چکیده
We calculate renormalization constants ZH,w, the Higgs and W–boson mass and tadpole counterterms in the on–mass-shell renormalization scheme to two loops in the heavy–Higgs– boson limit mH ≫ MW . Explicit analytic formulae are presented for the two–loop integrals with masses, which are not known in the literature. As an application, the analytic expression for the two–loop leading correction to the fermionic Higgs boson width is obtained.

نقض CP و گذار فاز الکتروضعیف در مدل دو هیگزی
In this paper, an analytic treatment of electroweak phase transition is proposed within the two-Higgs doublet model. This phase transition occurs in one stage and is strongly first order. Therefore, it can be applied to the electroweak baryogenesis scenario, whereas the standard model cannot provide this condition considering the experimental data. Also, we study CP violation which is one of th...
متن کاملThe Littlest Higgs Model and One-Loop Electroweak Precision Constraints
We present in this talk the one-loop electroweak precision constraints in the Littlest Higgs model, including the logarithmically enhanced contributions from both fermion and scalar loops. We find the one-loop contributions are comparable to the tree level corrections in some regions of parameter space. A low cutoff scale is allowed for a non-zero triplet VEV. Constraints on various other param...

We consider the Lorentz violating extension of the standard model introduced by D. Colladay and V. A. Kostelecky. In this framework, we obtain all Feynman rules for the electroweak part of the standard model extension (SME), for the first time. Among the new obtained interactions one finds new vertices for the Higgs boson that is interesting in the phenomenology of the Higgs particle.
متن کاملStability of Subsequent-to-Leading-Logarithm Corrections to the Effective Potential for Radiative Electroweak Symmetry Breaking
We demonstrate the stability under subsequent-to-leading logarithm corrections of the quartic scalar-field coupling constant λ and the running Higgs boson mass obtained from the (initially massless) effective potential for radiatively broken electroweak symmetry in the single-Higgs-Doublet Standard Model. Such subsequent-toleading logarithm contributions are systematically extracted from the re...
متن کاملFinite Temperature Effective Potential to Order g 4 , λ 2 and the Electroweak Phase Transition
The standard model effective potential is calculated at finite temperature to order g, λ and a complete zero temperature renormalization is performed. In comparison with lower order calculations the strength of the first order phase transition has increased dramatically. This effect can be traced back to infrared contributions from typical non-Abelian diagrams and to the infrared behaviour of t...
