Flux Compactifications, dS Vacua and the Swampland
Christoph Roupec
One of the main goals of the field of string phenomenology is to describe the properties of our spacetime in low-energy effective models related to and consistent with string theor…
Non-supersymmetric branes
Niccolò Cribiori, Christoph Roupec, Magnus Tournoy +2
We discuss how to incorporate non-supersymmetric branes in compactifications of type II string theories. We particularly focus on flux compactifications on stru…
Constructing the Supersymmetric anti-D3-brane action in KKLT
Niccolò Cribiori
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 i…
de Sitter Minima from M theory and String theory
Niccolò Cribiori, Renata Kallosh, Andrei Linde +1
We study M-theory compactification on in the presence of a seven-flux, metric fluxes and KK monopoles. The effective four-dimensional supergravity…
Mass Production of IIA and IIB dS Vacua
Niccolò Cribiori, Renata Kallosh, Andrei Linde +1
We describe several applications of the recently proposed mass production procedure, where multiple moduli are stabilized in a dS vacuum, in supergravity models inspired by string…
Uplifting Anti-D6-brane
Niccolò Cribiori, Renata Kallosh, Christoph Roupec +1
A simple, KKLT-like construction of de Sitter vacua in type IIA string theory is presented in an STU model with guidance from string theory U-duality and with an uplifting anti-D6-…
