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…
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…
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…
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…
