We present a holographic dual of four-dimensional, large N c QCD with massless flavors.
This model is constructed by placing Nf probe D8-branes into a D4 background, where …

Using a 10D lift of nonperturbative volume stabilization in type IIB string theory, we study the
limitations for obtaining de Sitter vacua. Based on this we find that the simplest Kachru …

A bstract The role of the\(\overline {\mathrm {D} 3}\) brane in providing de Sitter vacua with
spontaneously broken supersymmetry in the KKLT construction is clarified. The first step in …

As a top-down holographic approach, the D4/D8 model is expected to be a holographic
version of QCD, since it almost includes all the elementary features of QCD based on string …

We discuss the four-dimensional N= 1 effective approach in the study of warped type II flux
compactifications with SU (3)× SU (3)-structure to AdS 4 or flat Minkowski space-time. The …

We study the conditions to have supersymmetric D-branes on general Script N= 1
backgrounds with Ramond-Ramond fluxes. These conditions can be written in terms of the …

A bstract We study the imprint of higher spin supermultiplets on cosmological correlators,
namely the non-Gaussianity of the cosmic microwave background. Supersymmetry is used …

The understanding of the fermionic sector of the world-volume D-brane dynamics on a
general background with fluxes is crucial in several branches of string theory like, for …

We discuss a novel strategy to construct 4D Script N= 0 stable flux vacua of type II string
theory, based on the existence of BPS bounds for probe D-branes in some of these …

A bstract In this note we revisit some of the recent 10d and 4d arguments suggesting that the
uplifting of supersymmetric AdS vacua leads to a flattening of the potential, preventing the …
