Supersymmetry, p-brane duality, and hidden spacetime dimensions. [PDF]

Physical Review D, Particles and fields, 1996
A global superalgebra with 32 supercharges and all possible central extensions is studied in order to extract some general properties of duality and hidden dimensions in a theory that treats $p$-branes democratically.

Topology change and heterotic flux vacua

Journal of High Energy Physics
We investigate the interrelation between topology and Narain T-duality of heterotic flux vacua. We present evidence that all 5 and 4-dimensional Minkowski space heterotic flux backgrounds with 8 supercharges have a locus in the moduli space with a T-dual

Modular forms and SL(2, ℤ)-covariance of type IIB superstring theory

Journal of High Energy Physics, 2019
The local higher-derivative interactions that enter into the low-energy expansion of the effective action of type IIB superstring theory with constant complex modulus generally violate the U(1) R-symmetry of IIB supergravity by q U units.

N $$ \mathcal{N} $$ = 1 conformal duals of gauged E n MN models

Journal of High Energy Physics, 2020
We suggest three new N $$ \mathcal{N} $$ = 1 conformal dual pairs. First, we argue that the N $$ \mathcal{N} $$ = 2 E 6 Minahan-Nemeschansky (MN) theory with a USp(4) subgroup of the E 6 global symmetry conformally gauged with an N $$ \mathcal{N} $$ = 1 ...

Conformal manifolds and 3d mirrors of (D n , D m ) theories

Journal of High Energy Physics, 2022
The Argyres-Douglas (AD) theories of type (D n , D m ), realized by type IIB geometrical engineering on a single hypersurface singularity, are studied. We analyze their conformal manifolds and propose the 3d mirror theories of all theories in this class ...

On Calabi‐Yau Manifolds at Strong Topological String Coupling

Fortschritte der Physik, Volume 72, Issue 12, December 2024.
Abstract It was recently shown that integrating out M2 states on Calabi‐Yau manifolds captures non‐perturbative topological string physics in the free energy. In this note, It has been shown that the resulting expression manifests a certain duality symmetry: the free energy at strong string coupling is equal to the Calabi‐Yau period at weak string ...

SUSY breaking in monopole quivers

Journal of High Energy Physics, 2019
We study 3d monopole quivers, theories with product gauge groups interacting through monopole superpotentials and we observe that they are a natural setup for the study of the spontaneous breaking of 3d N $$ \mathcal{N} $$ = 2 supersymmetry.

Non-perturbative tests of duality cascades in three dimensional supersymmetric gauge theories

Journal of High Energy Physics, 2021
It has been conjectured that duality cascade occurs in the N $$ \mathcal{N} $$ = 3 supersymmetric Yang-Mills Chern-Simons theory with the gauge group U(N) k × U(N + M) −k coupled to two bi-fundamental hypermultiplets. The brane picture suggests that this

de Sitter State in Heterotic String Theory

Fortschritte der Physik, Volume 72, Issue 11, November 2024.
Abstract Recent no‐go theorems have ruled out four‐dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well‐defined Wilsonian effective action and other related phenomena also appear to rule out such time‐dependent vacua with de Sitter isometries, even in the presence of quantum corrections.

Gauge/gravity duality and meta-stable dynamical supersymmetry breaking [PDF]

, 2006
We engineer a class of quiver gauge theories with several interesting features by studying D-branes at a simple Calabi-Yau singularity. At weak 't Hooft coupling we argue using field theory techniques that these theories admit both supersymmetric vacua ...
