Abstract. In this paper, we consider high scale (100 TeV) supersymmetry (SUSY) breaking and realize the idea of hilltop supernatural inflation in concrete particle physics models based on flipped-SU(5) and Pati-Salam models in the framework of supersymmetric grand unified theories (SUSY GUTs). The inflaton can be a flat direction including right-handed sneutrino and the waterfall field is a GUT Higgs. The spectral index is n s = 0.96 which fits very well with recent data by PLANCK satellite. There is no both thermal and non-thermal gravitino problems. Non-thermal leptogenesis can be resulted from the decay of right-handed sneutrino which plays (part of) the role of inflaton.

“…In the intersecting D-brane model building on Type II orientifolds where the SU(5) gauge symmetry is broken down to the SM gauge symmetry by D-brane splitting [49][50][51], and in the Mtheory on S 1 /Z 2 with Calabi-Yau manifold compactifications where the SU(5) and SO (10) gauge symmetries are respectively broken down to the SU(3) the vector-like particles in the complete GUT representations, i.e., the zero modes of some vector-like particles will be projected out. In the F-theory GUTs [20][21][22][23][24][25][26][27][28][29][30][31][32], we can also obtain the vector-like particles that do not form complete GUT multiplets. In fact, the SU(5) models, flipped SU(5) × U(1) X models [55][56][57][58][59], and SU(3)…”

“…models with additional vector-like particles have already been constructed locally in Ftheory [22,23,25,26,28,29,32]. Interestingly, we should emphasize that this is the reason why we can solve the doublet-triplet splitting problem in these kinds of model building.…”

“…Thus, the condition for gauge coupling unification in the flipped SU(5) × U(1) X models can be relaxed elegantly. To realize the string-scale gauge coupling unification in the free fermionic string constructions [58] or the decoupling scenario in the F-theory model building [26,28], we introduce the TeV-scale vector-like particles which form the complete flipped SU(5) × U(1) X multiplets [59]. To avoid the Landau pole problem for the strong coupling, we show that at the TeV scale, we can only introduce the vector-like particles (XF, XF ) or (XF, XF ) ⊕ (Xl, Xl) [59].…”

“…Moreover, in the F-theory SO(10) models where the gauge symmetry is broken down to the flipped SU(5) × U(1) X gauge symmetries by turning on the U(1) X flux, we can construct the flipped SU(5) × U(1) X models with vector-like particles in all the Cases in the Table VI except the Case (5) [26,28]. Interestingly, the indices k for the gaugino mass relations are zero for all the Cases except the Case (4) with messenger fields (Xh, Xh).…”

In Grand Unified Theories (GUTs) from orbifold and various string constructions the generic vector-like particles do not need to form complete SU (5) or SO(10) representations. To realize them concretely, we present orbifold SU (5) models, orbifold SO(10) models where the gauge symmetry can be broken down to flippedsymmetries, and F-theory SU (5) models. Interestingly, these vector-like particles can be at the TeV-scale so that the lightest CP-even Higgs boson mass can be lifted, or play the messenger fields in the Gauge Mediated Supersymmetry Breaking (GMSB). Considering GMSB, ultraviolet insensitive Anomaly Mediated Supersymmetry Breaking (AMSB), and the deflected AMSB, we study the general gaugino mass relations and their indices, which are valid from the GUT scale to the electroweak scale at one loop, in the SU (5) models, the flipped SU (5) × U (1) X models, and the Pati-Salam SU (4) C × SU (2) L × SU (2) R models. In the deflected AMSB, we also define the new indices for the gaugino mass relations, and calculate them as well. Using these gaugino mass relations and their indices, we may probe the messenger fields at intermediate scale in the GMSB and deflected AMSB, determine the supersymmetry breaking mediation mechanisms, and distinguish the four-dimensional GUTs, orbifold GUTs, and F-theory GUTs.
