Journal of High Energy Physics, 2017 : We examine the double-trace spectrum of N = 4 super Yang-Mills theory in the supergravity limit. At large N double-trace operators exhibit degeneracy. By considering free-(cid:12)eld and tree-level supergravity contributions to four-point functions of ...

The cosmological constant in supergravity [PDF]
The European Physical Journal C, 2018 We propose a supersymmetrisation of the cosmological constant in ordinary $$N=1$$N=1 supergravity that breaks supersymmetry spontaneously by a constant Fayet-Iliopoulos (FI) term associated to a U(1) symmetry.

Quantum supergravity, supergravity anomalies and string phenomenology [PDF]
Nuclear Physics B, 2016 I discuss the role of quantum effects in the phenomenology of effective supergravity theories from compactification of the weakly coupled heterotic string. An accurate incorporation of these effects requires a regularization procedure that respects local

Minimal Constrained Supergravity [PDF]
Physics Letters B, 2016 We describe minimal supergravity models where supersymmetry is non-linearly realized via constrained superfields. We show that the resulting actions differ from the so called "de Sitter" supergravities because we consider constraints eliminating directly the auxiliary fields of the gravity multiplet.

Conformal Interactions Between Matter and Higher‐Spin (Super)Fields
Fortschritte der Physik, Volume 71, Issue 1, January 2023., 2023 Abstract In even spacetime dimensions, the interacting bosonic conformal higher‐spin (CHS) theory can be realised as an induced action. The main ingredient in this definition is the model S[φ,h]$\mathcal {S}[\varphi ,h]$ describing a complex scalar field φ coupled to an infinite set of background CHS fields h, with S[φ,h]$\mathcal {S}[\varphi ,h ...

Mass Hierarchies and Quantum Gravity Constraints in DKMM‐refined KKLT
Fortschritte der Physik, Volume 71, Issue 1, January 2023., 2023 Abstract We carefully revisit the mass hierarchies for the KKLT scenario with an uplift term from an anti D3‐brane in a strongly warped throat. First, we derive the bound resulting from what is usually termed “the throat fitting into the bulk” directly from the Klebanov‐Strassler geometry.

Supersymmetric domain walls in maximal 6D gauged supergravity I
European Physical Journal C: Particles and Fields, 2021 We find a large class of supersymmetric domain wall solutions from six-dimensional $$N=(2,2)$$ N = ( 2 , 2 ) gauged supergravity with various gauge groups.

Journal of High Energy Physics, 2017 Supergravity with eight supercharges in a four-dimensional Euclidean space is constructed at the full non-linear level by performing an off-shell time-like reduction of five-dimensional supergravity. The resulting four-dimensional theory is realized off-shell with the Weyl, vector and tensor supermultiplets and a corresponding multiplet calculus ...
