Chiral global embedding of Fibre Inflation with uplift
Michele Cicoli, Antonella Grassi, Osmin Lacombe +1
We carefully analyse the challenges posed by the construction of type IIB chiral global embeddings of Fibre Inflation with uplift to a de Sitter vacuum. We pre…
Higher-derivative supersymmetric effective field theories
Osmin Lacombe, Lorenzo Paoloni, Francisco G. Pedro
In this paper we study higher-derivative supersymmetric effective field theories focusing on the systematic procedure for the elimination of ghosts from the spectrum. Particular at…
Flux vacua in type IIB compactifications on orbifolds: their finiteness and minimal string coupling
Ignatios Antoniadis, Anthony Guillen, Osmin Lacombe
We perform a detailed study of (supersymmetric) moduli stabilisation in type IIB toroidal orientifolds with fluxes. We provide strong evidence towards exhaustion of the finite numb…
Are theories really relevant to cosmology?
Osmin Lacombe, Shinji Mukohyama, Josef Seitz
We examine theories that directly couple the curvature or with the matter sector in the action, in addition to the universal coupling. We argue…
