Abstract

Here, we describe how quartic (λφ⁴) inflation with non-minimal coupling to gravity is realized in realistic supersymmetric SO(10)models. In a well-motivated example the 16 -$$\overline{16}$$ Higgs multiplets, which break SO(10) to SU(5) and yield masses for the right-handed neutrinos, provide the inflaton field φ. Thus, leptogenesis is a natural outcome in this class of SO(10) models. Moreover, the adjoint (45-plet) Higgs also acquires a GUT scale value during inflation so that the monopole problem is evaded. The scalar spectral index n_s in good agreement with the observations and r, the tensor to scalar ratio, is predicted for realistic values of GUT parameters to be of order 10^-3-10^-2.

Inflation, proton decay, and Higgs-portal dark matter in $$$$SO(10) \times U(1)_\psi $$$$

Journal Article Okada, Nobuchika ; Raut, Digesh ; Shafi, Qaisar - European Physical Journal. C, Particles and Fields

We propose a simple non-supersymmetric grand unified theory (GUT) based on the gauge group SO(10)×U(1)_ψ. The model includes 3 generations of fermions in 16 (+1), 10 (–2) and 1 (+4) representations. The 16-plets contain Standard Model (SM) fermions plus right-handed neutrinos, and the 10-plet and the singlet fermions are introduced to make the model anomaly-free. Gauge coupling unification at M_GUT≃5×10¹⁵ - 10¹⁶ GeV is achieved by including an intermediate Pati–Salam breaking at M_I ≃ 10¹² – 10¹¹ GeV, which is a natural scale for the seesaw mechanism. For M_I ≃ 10¹² – 10¹¹, proton decay will be tested by themore »« less

Susy seesaw inflation and NMSO(10)GUT

Journal Article Aulakh, Charanjit S. - AIP Conference Proceedings

We show that Supersymmetric models with Type I seesaw neutrino masses support slow roll inflection point inflation. The inflaton is the D-flat direction labelled by the chiral invariant HLN composed of the Higgs(H), slepton(L) and conjugate sneutrino(N) superfields. The scale of inflation and fine tuning is set by the conjugate neutrino Majorana mass M{sub {nu}{sup c}}{approx} 10{sup 6} - 10{sup 12} GeV. The cubic term in the (quartic) inflaton potential is dominantly from superpotential (not soft Susy breaking) couplings. The tuning conditions are thus insensitive to soft supersymmetry breaking parameters and are generically much less stringent than for previous 'A-term'more »« less

Realistic inflation in no-scale U(1)_R symmetric flipped SU(5)

Journal Article Abid, Mian Muhammad Azeem ; Mehmood, Maria ; Rehman, Mansoor Ur ; ... - Journal of Cosmology and Astroparticle Physics

We have realized non-minimal Higgs inflation and standard hybrid inflation in the supersymmetric flipped SU(5) model with U(1)_R symmetry using the no-scale form of the Kähler potential. In non-minimal Higgs inflation the waterfall Higgs field plays the role of inflaton, and in standard hybrid inflation the gauge singlet field S is employed as an inflaton. The predictions of both models are in good agreement with the Planck 2018 data. For numerical calculations we have fixed the gauge symmetry breaking scale, M, around 2 × 10¹⁶ GeV. In both models the inflaton field values are constrained below m_P. The tensor tomore »« less

Inflection-point $B - L$ Higgs inflation

Journal Article Okada, Nobuchika ; Raut, Digesh - Physical Review D

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≲M_Pl). 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 in its RG evolution, namely λ(_ΦI)≃0 and β_λ(ΦI)≃0, where β_λ is the beta-function of the quartic coupling. As an example, we consider the minimal gauged B-L extended Standard Model at the TeV scale, where we identify the B-L Higgs field as the inflaton field. For a successful inflection-point inflation, which is consistent with the current cosmological observations, the mass ratios among the Z' gauge boson, the right-handed neutrinos and the B-L Higgs boson are fixed. Our scenario can be tested in the future collider experiments such as the High-Luminosity LHC and the SHiP experiments. Finally, in addition, the inflection-point inflation provides a unique prediction for the running of the spectral index α≃-2.7×10^-3(more »« less
