Title: Gravity waves and gravitino dark matter in μ-hybrid inflation

Abstract

We propose a novel reformulation of supersymmetric (more precisely μ-) hybrid inflation based on a local U(1) or any suitable extension of the minimal supersymmetric standard model (MSSM) which also resolves the μ problem. We employ a suitable Kahler potential which effectively yields quartic inflation with non-minimal coupling to gravity. Imposing the gravitino Big Bang Nucleosynthesis (BBN) constraint on the reheat temperature ( GeV) and requiring a neutralino LSP, the tensor to scalar ratio (r) has a lower bound . The U(1) symmetry breaking scale lies between 108 and 1012 GeV. We also discuss a scenario with gravitino dark matter whose mass is a few GeV.

Consistent cosmology with Higgs thermal inflation in a minimal extension of the MSSM

Journal Article Hindmarsh, Mark ; Jones, D.R. Timothy, - Journal of Cosmology and Astroparticle Physics

We consider a class of supersymmetric inflation models, in which minimal gauged F-term hybrid inflation is coupled renormalisably to the minimal supersymmetric standard model (MSSM), with no extra ingredients; we call this class the ''minimal hybrid inflationary supersymmetric standard model'' (MHISSM). The singlet inflaton couples to the Higgs as well as the waterfall fields, supplying the Higgs μ-term. We show how such models can exit inflation to a vacuum characterised by large Higgs vevs, whose vacuum energy is controlled by supersymmetry-breaking. The true ground state is reached after an intervening period of thermal inflation along the Higgs flat direction, whichmore »« less

μ-term hybrid inflation and split supersymmetry

Journal Article Okada, Nobuchika ; Shafi, Qaisar - Physics Letters B

We consider μ-term hybrid inflation which, in its minimal format with gravity mediated supersymmetry breaking, leads to split supersymmetry. The MSSM μ-term in this framework is larger than the gravitino mass m_G, and successful inflation requires m_G (and hence also |μ|) ≳ 5 × 10⁷ GeV, such that the gravitino decays before the LSP neutralino freezes out. Assuming universal scalar masses of the same order as m_G, this leads to split supersymmetry. The LSP wino with mass ≃ 2 TeV is a plausible dark matter candidate, the gluino may be accessible at the LHC, and the MSSM parameter β ≃more »« less

Shifted μ -hybrid inflation, gravitino dark matter, and observable gravity waves

Journal Article Lazarides, George ; Rehman, Mansoor Ur ; Shafi, Qaisar ; ... - Physical Review. D.

We investigate supersymmetric hybrid inflation in a realistic model based on the gauge symmetry SU(4)_c × SU(2)_L × SU(2)_R. The minimal supersymmetric standard model (MSSM) μ term arises, following Dvali, Lazarides, and Shafi, from the coupling of the MSSM electroweak doublets to a gauge singlet superfield which plays an essential role in inflation. The primordial monopoles are inflated away by arranging that the SU(4)_c × SU(2)_L × SU(2)_R symmetry is broken along the inflationary trajectory. The interplay between the (above) μ coupling, the gravitino mass, and the reheating following inflation is discussed in detail. We explore regions of the parametermore »« less

$μ$ -hybrid inflation, gravitino dark matter, and stochastic gravitational wave background from cosmic strings

Journal Article Afzal, Adeela ; Ahmed, Waqas ; Rehman, Mansoor Ur ; ... - Physical Review D

We present a successful realization of supersymmetric μ-hybrid inflation model based on a gauged U(1)_B–L extension of the minimal supersymmetric standard model, with the soft supersymmetry breaking terms are playing an important role. Successful nonthermal leptogenesis with gravitino dark matter yields a reheat temperature in the range 2 × 10⁷ ≲ T_R ≲ 5 × 10⁹ GeV. This corresponds to the predictions 2×10-18 ≲ r ≲ 4×10-13 for the tensor to scalar ratio, and -2 × 10^-6 ≲ dn_s/d ln k ≲ -5 × 10^-11 for the running of the scalar spectral index.

Gravitino dark matter and the lithium primordial abundance within a pre-BBN modified expansion

Journal Article Bailly, Sean - Journal of Cosmology and Astroparticle Physics

We present supersymmetric scenarios with gravitino LSP and stau NLSP in the case of a non-standard model of cosmology with the addition of a dark component in the pre-BBN era. In the context of the standard model of cosmology, gravitino LSP has drawn quite some attention as it is a good candidate for dark matter. It is produced in scattering processes during reheating after inflation and from the decay of the stau. With a long lifetime, the stau decays during Big Bang Nucleosynthesis. It is strongly constrained by the abundance of light elements but can however address the known ''BBNmore »« less
