A Duality Web for Non-Supersymmetric Strings
Zihni Kaan Baykara, Matilda Delgado, Emilian Dudas +2
Motivated by the recently proposed geometric descriptions of 0A and 0B in M-theory and F-theory, we propose a web of duality among non-supersymmetric strings. In particular we argu…
M-theory on as Type 0A
Zihni Kaan Baykara, Emilian Dudas, Cumrun Vafa
We propose an exotic geometric M-theory dual for the weak coupling Type 0A string: compactification on a sub-Planckian (two circles connected at a point), where stron…
The Cosmological Constant and Dark Dimensions from Non-Supersymmetric Strings
Emilian Dudas, Susha Parameswaran, Marco Serra
We present a string theory construction in which the particle physics contributions to the one-loop vacuum energy exactly cancel, whilst the gravitational contributions are suppres…
Supersymmetry Breaking with Fields, Strings and Branes
E. Dudas, J. Mourad, A. Sagnotti
The first part of this review tries to provide a self-contained view of supersymmetry breaking from the bottom-up perspective. We thus describe N=1 supersymmetry in four dimensions…
A unique coupling of the massive spin-2 field to supergravity
Guillaume Bossard, Gabriele Casagrande, Emilian Dudas +1
We show that the coupling of a massive spin-2 field to undeformed N=1 supergravity in four dimensions is unique, leading to a specific non-minimal coupling to the Riemann tensor. T…
Twisted Orientifold planes and S-duality without supersymmetry
Guillaume Bossard, Gabriele Casagrande, Emilian Dudas
We construct a novel orientifold of type IIB string theory that breaks all supersymmetries. It is a closed string theory without open sector and it can be understood as a Scherk-Sc…
Rigid Vacua with Brane Supersymmetry Breaking
C. Angelantonj, C. Condeescu, E. Dudas +1
We construct new string vacua featuring Brane Supersymmetry Breaking, based on orientifolds with planes and branes. Differen…
Properties of Nilpotent Supergravity
E. Dudas, S. Ferrara, A. Kehagias +1
We construct Supergravity models where the goldstino multiplet has a gravitational origin, being dual to the chiral curvature superfield. Supersymmetry is nonlinearly realized due…
Orientifolds of String Theory Melvin backgrounds
C. Angelantonj, E. Dudas, J. Mourad
We study the dynamics of type I strings on Melvin backgrounds, with a single or multiple twisted two-planes. We construct two inequivalent types of orientifold models that correspo…
D-branes in String theory Melvin backgrounds
E. Dudas, J. Mourad
We determine the consistent D-brane configurations in type II nonsupersymmetric Melvin Background. The D-branes are analysed from three complementary points of view: the effective…
D-branes in non-tachyonic 0B orientifolds
E. Dudas, J. Mourad
We determine all D-branes in the non-tachyonic 0'B orientifold, examine their world-volume anomalies and study orbifold compactifications. We find that the spectrum of the D-branes…
Type I vacua with brane supersymmetry breaking
C. Angelantonj, I. Antoniadis, G. D'Appollonio +2
We show how chiral type I models whose tadpole conditions have no supersymmetric solution can be consistently defined introducing antibranes with non-supersymmetric world volumes.…
Partial breaking of supersymmetry, open strings and M-theory
I. Antoniadis, G. D'Appollonio, E. Dudas +1
We study total and partial supersymmetry breaking by freely acting orbifolds, or equivalently by Scherk-Schwarz compactifications, in type I string theory. In particular, we descri…
Solitons in the Horava-Witten supergravity
E. Dudas, J. Mourad
We study classical BPS five-brane solutions in the Horava-Witten supergravity. The presence of the eleventh dimension add a new feature, namely the dependence of the solution on th…
