Inflection-point Higgs Inflation
Inflection-point inflation is an interesting possibility to realize a successful slow-roll inflation when inflation is driven by a single scalar field with its initial value below the Planck mass (φI . MP l). In order for a renormalization group (RG) improved effective λφ4 potential to develop an inflection-point, the quartic coupling λ(φ) must exhibit a minimum with an almost vanishing value i...
متن کاملHiggs-mass predictions and electroweak precision observables in the Standard Model and the MSSM∗
Higher-order results for electroweak precision observables in the Standard Model are analyzed in view of the experimental accuracies achievable at the present and the next generation of colliders, and the indirect prediction of the Higgs-boson mass from the precision data is discussed. Within the MSSM, two-loop results for the lightest CP-even Higgs-boson mass are confronted with the exclusion ...
متن کاملElectroweak Baryogenesis and the Standard Model
Electroweak baryogenesis is addressed within the context of the standard model of particle physics. Although the minimal standard model has the means of fulfilling the three Sakharov’s conditions, it falls short to explaining the making of the baryon asymmetry of the universe. In particular, it is demonstrated that the phase of the CKM mixing matrix is an insufficient source of CP violation. Th...
متن کاملStandard Model of Electroweak Interactions
It is shown that the gauge fixings of the Z and the W fields and three scalars are via nonconserved axial-vector and charged vector currents of massive fermions dynamically generated by fermion masses in the SM of EW interactions. The top quark mass provides enough strength for this chiral symmetry breaking. The masses of the three scalars are determined to be about 1014 GeV. These scalars have...
متن کاملThe Electroweak Chiral Lagrangian for the Standard Model with a heavy Higgs
The most general chiral Lagrangian for electroweak interactions with the complete set of SU(2)L × U(1)Y invariant operators up to dimension four is considered. The two-point and three-point functions with external gauge fields are derived from this effective chiral Lagrangian to one-loop order in a generic Rξ-gauge. The same set of Green’s functions are paralelly studied in the renormalizable s...
