“…Useful information on the form of the Kähler potential can be obtained by studying the derivative couplings involving (derivatives of) the closed string axions and the open string fermions, both for the D3-brane and the anti-D3-brane. A detailed discussion can be found in [35], but an interesting result is reported also here. In the component action (2.23), the couplings of λ and χ i to ∂ µ Re(T ) and to ∂ µ Re(U A ), which is encoded in the spin connection term in the last line, have the same relative sign between the bilnear in λ and in χ i .…”

“…Following [6,29], one can decompose the spinor θ into four-dimensional Weyl spinors, namely an SU(3)-singlet P L λ and a triplet P L χ i . The dimensional reduction of the kinetic term and of the last line of (2.17) was performed in [6], while for the remaining terms one can see [35].…”

The derivation of the complete anti-D3-brane low energy effective action in KKLT is reviewed. All worldvolume fields are included, together with the background moduli. The result is recast into a manifest supersymmetric form in terms of the three independent functions of N = 1 supergravity in four dimensions: the Kähler potential, the superpotential and the gauge kinetic function. The latter differs from the expression one would expect by analogy with the D3-brane case.

“…Secondly, with the help of an anti-D3-brane, one can uplift this anti-de Sitter vacuum with a negative cosmological constant to a de Sitter vacuum with a positive cosmological constant. In four-dimensional N = 1 supergravity, this second step can be described by a non-linearly realized supersymmetry and a nilpotent multiplet [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. A detailed derivation of the KKLT construction of de Sitter vacua from ten dimensions was presented recently in [24].…”

A three-step procedure is proposed in type IIA string theory to stabilize multiple moduli in a dS vacuum. The first step is to construct a progenitor model with a localized stable supersymmetric Minkowski vacuum, or a discrete set of such vacua. It can be done, for example, using two non-perturbative exponents in the superpotential for each modulus, as in the KL model [1]. A large set of supersymmetric Minkowski vacua with strongly stabilized moduli is protected by a theorem on stability of these vacua in absence of flat directions [2]. The second step involves a parametrically small downshift to a supersymmetric AdS vacuum, which can be achieved by a small change of the superpotential. The third step is an uplift to a dS vacuum with a positive cosmological constant using the D6-brane contribution [3,4]. Stability of the resulting dS vacuum is inherited from the stability of the original supersymmetric Minkowski vacuum if the supersymmetry breaking in dS vacuum is parametrically small [2,5].

“…Nilpotent superfields have proved to be an invaluable tool for phenomenological supergravity: they can be used for de Sitter uplifting without scalar fields [1][2][3][4], inflationary model building [5][6][7][8][9][10][11][12][13], and describing string low-energy effective theories in a manifestly supersymmetric way [14][15][16][17][18][19][20][21].…”

We find new realizations of Volkov-Akulov-Starobinsky supergravity, i.e. Starobinsky inflationary models in supergravity coupled to a nilpotent superfield describing Volkov-Akulov goldstino. Our constructions are based on the no-scale Kähler potential K = −3 log(T + T ) for the inflaton field, and can describe de Sitter vacuum after inflation where supersymmetry is broken by the goldstino auxiliary component. In fact, we show that a more general class of models with K = −α log(T + T ) for 3 ≤ α 6.37 can accomodate Starobinsky-like inflation with the universal prediction n s 1 − 2 Ne and r 4α (α−2) 2 N 2 e , while for 6.37 α 7.23 viable hilltop inflation is possible (with n s and r close to the above expressions). We derive the full component action and the masses of sinflaton, gravitino, and inflatino that are generally around the inflationary Hubble scale. Finally, we show that one of our models can be dualized into higher-derivative supergravity with constrained chiral curvature superfield. arXiv:2001.06617v3 [hep-th] 12 Mar 20201 Recently an alternative approach (without nilpotent superfields) to Volkov-Akulov supergravity in de Sitter space was proposed, that uses unimodular supergravity [30,31].2 Although the original potential has tachyonic instability at C = 0, it can be removed by adding quartic correction ∼ |C| 4 to the Kähler potential (3), as was shown in Ref. [36].3 In Ref.[9] the authors also propose a different class of Volkov-Akulov-Starobinsky supergravity models where the Kähler potential has the simplest shift-symmetric form, K = (T + T ) 2 /2.
