Consistent truncation of eleven-dimensional supergravity on S 8 × S 1
Journal of High Energy PhysicsEleven-dimensional supergravity on S 8 × S 1 is conjectured to be dual to the M-theory matrix model. We prove that the dynamics of a subset of fluctuations around this background is consistently described by D = 2 SO(9) gauged maximal supergravity.

Off-shell no-go theorems for higher dimensional supersymmetries and supergravities
Physics Letters B, 1983 Abstract By a simple fermion counting argument we show in which space-time dimensions the existence of off-shell supersymmetric Yang-Mills and supergravity theories with an off-shell supersymmetry algebra without “central charges” are allowed. In particular we show that the maximally extended theories require “central charges” or lose explicit ...

Dual versions of higher-dimensional supergravities and anomaly cancellations in lower dimensions
Nuclear Physics B, 1986 Abstract Supergravity theories with higher-rank tensors dual to the ordinary second-rank tensors (dual versions) are given in D = 8 and 6. The special role of higher-rank tensors in the dual versions for anomaly cancellations in lower even dimensions is studied by inspecting examples of D = 10, N = 1 dual version compactified to D = 6, and D

, 2016 Dans cette thèse, nous présentons des constructions explicites de la correspondance AdS/CFT dans le contexte de la théorie des cordes de type II. Ces constructions sont visées à mieux comprendre aspects de la physique nonperturbative de théories des champs superconformes à d = 6,5,4 dimensions.

Boundary terms and conserved charges in higher-derivative gauged supergravity [PDF]
Journal of High Energy Physics, 2023 We address some issues in higher-derivative gauged supergravity with Chern-Simons terms, focusing on the five-dimensional case. We discuss the variational problem with Dirichlet boundary conditions as well as holographic renormalization in asymptotically

Consistent truncations in higher derivative supergravity [PDF]
Journal of High Energy Physics, 2023 We consider the torus reduction of heterotic supergravity in the presence of four-derivative corrections. In particular, the reduction on Tn generically leads to a half-maximal supergravity coupled to n vector multiplets, and we show that it is ...

Cubic and higher-order supergravity couplings for AdS vacua using Exceptional Field Theory [PDF]
Journal of High Energy Physics, 2023 We show how to use Exceptional Field Theory to efficiently compute n-point couplings of all Kaluza-Klein modes for vacua that can be uplifted from maximal gauged supergravities to 10/11 dimensions via a consistent truncation.

Journal of High Energy Physics, 2022 Supergravity brane solutions allow for a generalised type of Kaluza-Klein reduction onto brane worldvolumes. The known replacement of a flat worldvolume metric by a Ricci-flat metric constitutes a consistent Kaluza-Klein truncation of the starting higher-
