Inflection-point sgoldstino inflation in no-scale supergravity
نویسندگان
چکیده
We propose a modification of no-scale supergravity models which incorporates sgoldstino stabilization and supersymmetry (SUSY) breaking with tunable cosmological constant by introducing Kahler potential yields kinetic pole order one. The resulting scalar may develop an inflection point, close to inflationary period can be realized for subplanckian field values consistently the observational data. For central value spectral index ns, necessary tuning is 10^-6, tensor-to-scalar ratio tiny whereas running ns around -3x10^-3. Our proposal compatible high-scale SUSY results LHC on Higgs boson mass.

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 کاملLinking Starobinsky-type inflation in no-scale supergravity to MSSM
A novel realization of the Starobinsky inflationary model within a moderate extension of the Minimal Supersymmetric Standard Model (MSSM) is presented. The proposed superpotential is uniquely determined by applying a continuous R and a Z2 discrete symmetry, whereas the Kähler potential is associated with a no-scale-type SU(54, 1)/ SU(54)×U(1)R×Z2 Kähler manifold. The inflaton is identified with...
متن کاملGeneral sGoldstino inflation
We prove that all inflationary models, including those with dark energy after the end of inflation, can be embedded in minimal supergravity with a single chiral superfield. Moreover, the amount of supersymmetry breaking is independently tunable due to a degeneracy in the choice for the superpotential. The inflaton is a scalar partner of the Goldstino in this set-up. We illustrate our general pr...
متن کاملString no-scale supergravity
We explore the postulates of string no-scale supergravity in the context of free-fermionic string models. The requirements of vanishing vacuum energy, flat directions of the scalar potential, and stable no-scale mechanism impose strong restrictions on possible string no-scale models, which must possess only two or three moduli, and a constrained massless spectrum. The soft-supersymmetrybreaking...
متن کاملAlmost No-Scale Supergravity
We construct an explicit 5-dimensional supergravity model that realizes the ‘no scale’ mechanism for supersymmetry breaking with no unstable moduli. Supersymmetry is broken by a constant superpotential localized on a brane, and the radion is stabilized by Casimir energy from supergravity and massive hypermultiplets. If the standard model gauge and matter fields are localized on a brane, then vi...
