Title: Particle physics and cosmology of the string derived no-scale flipped SU(5)

Abstract

In a recent paper, we identified a cosmological sector of a flipped SU(5) model derived in the free fermionic formulation of the heterotic superstring, containing the inflaton and the goldstino superfields with a superpotential leading to Starobinsky type inflation, while SU(5) × U(1) is still unbroken. Here, we study the properties and phenomenology of the vacuum after the end of inflation, where the gauge group is broken to the Standard Model. We identify a set of vacuum expectation values, triggered by the breaking of an anomalous U(1)_A gauge symmetry at roughly an order of magnitude below the string scale, that solve the F and D-flatness supersymmetric conditions up to 6th order in the superpotential which is explicitly computed, leading to a successful particle phenomenology. In particular, all extra colour triplets become superheavy guaranteeing observable proton stability, while the Higgs doublet mass matrix has a massless pair eigenstate with realistic hierarchical Yukawa couplings to quarks and leptons. The supersymmetry breaking scale is constrained to be high, consistent with the non observation of supersymmetry signals at the LHC.

Symmetry breaking and reheating after inflation in no-scale flipped SU(5)

Journal Article Ellis, John ; Garcia, Marcos A. G. ; Nagata, Natsumi ; ... - Journal of Cosmology and Astroparticle Physics

No-scale supergravity and the flipped SU(5)×U(1) gauge group provide an ambitious prototype string-inspired scenario for physics below the string scale, which can accommodate the Starobinsky-like inflation favoured by observation when the inflaton is associated with one of the singlet fields associated with neutrino mass generation. During inflation, the vacuum remains in the unbroken GUT phase, and GUT symmetry breaking occurs later when a field with a flat direction (the flaton) acquires a vacuum expectation value. Inflaton decay and the reheating process depend crucially on GUT symmetry breaking, as decay channels open and close, depending on the value of the flatonmore »« less

Implications of symmetry breaking and phenomenology for super-string based models with gauge symmetry SU(3)/sub C/ x SU(2)/sub L/ x SU(2) x U(1) x SU(2) x U(1) x U(1)'

Journal Article McDonald, J - Int. J. Mod. Phys. A; (United States)

The authors discuss symmetry breaking and phenomenological aspects of rank 6 effective models in 4 dimensions, suggested by Calabi-Yau compactification of the heterotic E/sub 8/ x E/sub 8/ superstring, which have gauge group SU(3)/sub C/ x SU(2)/sub L/ x SU(2) x U(1)'. The simplest and most natural form of electroweak symmetry breaking for the softly broken effective SUSY theory is considered, and only those additions and alterations to the 27/sup 3/ based superpotential necessary to eliminate phenomenological problems are made. There are two physically distinct additional SU(2) factors, SU(2)/sub N/ and SU(2)/sub R/. The former has all gauge bosons electricallymore »« less

Superstring-inspired particle cosmology: inflation, neutrino masses, leptogenesis, dark matter & the SUSY scale

Journal Article Ellis, John ; Garcia, Marcos A. G. ; Nagata, Natsumi ; ... - Journal of Cosmology and Astroparticle Physics

We develop a string-inspired model for particle cosmology, based on a flipped SU(5)×U(1) gauge group formulated in a no-scale supergravity framework. The model realizes Starobinsky-like inflation, which we assume to be followed by strong reheating, with the GUT symmetry being broken subsequently by a light ‘flaton’ field whose decay generates a second stage of reheating. We discuss the production of gravitinos and the non-thermal contribution made by their decays to the density of cold dark matter, which is assumed to be provided by the lightest neutralino. We also discuss the masses of light and heavy neutrinos and leptogenesis. As discussedmore »« less

Sgoldstino-less inflation and low energy SUSY breaking

Journal Article Argurio, Riccardo ; Coone, Dries ; Mariotti, Alberto ; ... - Journal of Cosmology and Astroparticle Physics

We assess the range of validity of sgoldstino-less inflation in a scenario of low energy supersymmetry breaking. We first analyze the consistency conditions that an effective theory of the inflaton and goldstino superfields should satisfy in order to be faithfully described by a sgoldstino-less model. Enlarging the scope of previous studies, we investigate the case where the effective field theory cut-off, and hence also the sgoldstino mass, are inflaton-dependent. We then introduce a UV complete model where one can realize successfully sgoldstino-less inflation and gauge mediation of supersymmetry breaking, combining the α-attractor mechanism and a weakly coupled model of spontaneousmore »« less

Inflaton decay in supergravity

Journal Article Endo, Motoi ; Takahashi, Fuminobu ; Yanagida, T T ; ... - Physical Review. D, Particles Fields

We discuss inflaton decay in supergravity, taking account of the gravitational effects. It is shown that, if the inflaton has a nonzero vacuum expectation value, it generically couples to any matter fields that appear in the superpotential at the tree level, and to any gauge sectors through anomalies in the supergravity. Through these processes, the inflaton generically decays into the supersymmetry breaking sector, producing many gravitinos. The inflaton also directly decays into a pair of the gravitinos. We derive constraints on both inflation models and supersymmetry breaking scenarios for avoiding overproduction of the gravitinos. Furthermore, the inflaton naturally decays intomore »« less
