What if string theory has no de Sitter vacua?

UH Danielsson, TV Riet - International Journal of Modern Physics D, 2018 - World Scientific
We present a brief overview of attempts to construct de Sitter vacua in string theory and
explain how the results of this 20-year endeavor could point to the fact that string theory …

[HTML][HTML] Mesons in gauge/gravity duals

The tension between 10D supergravity and dS uplifts

FF Gautason, V Van Hemelryck… - Fortschritte der …, 2019 - Wiley Online Library
We elaborate on the recent work of Moritz et al. where it is argued that anti‐brane uplifting in
KKLT models never leads to dS vacua. This is due to flattening effects in the effective …

Confinement in (1+ 1) dimensions: a holographic perspective from I-branes

C Nunez, M Oyarzo, R Stuardo - Journal of High Energy Physics, 2023 - Springer
A bstract In this paper we holographically study the strongly coupled dynamics of the field
theory on I-branes (D5 branes intersecting on a line). In this regime, the field theory …

Toward de Sitter space from ten dimensions

J Moritz, A Retolaza, A Westphal - Physical Review D, 2018 - APS
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 …

We review recent progress in determining the effects of d-brane instantons in
supersymmetric compactifications of Type II string theory to four dimensions. We describe …

and dS

EA Bergshoeff, K Dasgupta, R Kallosh… - Journal of High Energy …, 2015 - Springer
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 …

Jumping through loops: on soft terms from large volume compactifications

M Berg, M Haack, E Pajer - Journal of High Energy Physics, 2007 - iopscience.iop.org
We subject the phenomenologically successful large volume scenario of hep-th/0502058 to
a first consistency check in string theory. In particular, we consider whether the expansion of …

A bstract The Kalb-Ramond field is an antisymmetric, rank-two tensor field which most
notably appears in the context of string theory, but has largely been unexplored in the …
