Supersymmetric Ground States of 3d $\mathcal{N}=4$ Gauge Theories on a Riemann Surface

SciPost Physics, 2022
This paper studies supersymmetric ground states of 3d $\mathcal{N}=4$ supersymmetric gauge theories on a Riemann surface of genus $g$. There are two distinct spaces of supersymmetric ground states arising from the $A$ and $B$ type twists on the ...

Non-Supersymmetric Gauge Theories from D-Branes in Type 0 String Theory

, 1999
We construct non-supersymmetric four dimensional gauge theories arising as effective theories of D-branes placed on various singularities in Type 0B string theory.

Grey‐Body Factors and Absorption Cross‐Sections of Scalar and Dirac Fields in the Vicinity of Dilaton‐De Sitter Black Hole

Fortschritte der Physik, Volume 74, Issue 1, January 2026.
Abstract The propagation of a massive scalar field and a massless Dirac field in the geometry of a dilaton–de Sitter black hole is investigated. Starting from the covariant perturbation equations, the corresponding effective potentials are presented and their dependence on the dilaton charge, field mass, and cosmological constant is analyzed. Using the

Flattening of the EFT-hedron: supersymmetric positivity bounds and the search for string theory

Journal of High Energy Physics
We examine universal positivity constraints on 2 → 2 scattering in 4d planar N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory with higher-derivative corrections. We present numerical evidence that the convex region of allowed Wilson coefficients (

Partition functions and fibering operators on the Coulomb branch of 5d SCFTs

Journal of High Energy Physics, 2023
We study 5d N $$ \mathcal{N} $$ = 1 supersymmetric field theories on closed five-manifolds M $$ \mathcal{M} $$ 5 which are principal circle bundles over simply-connected Kähler four-manifolds, M $$ \mathcal{M} $$ 4, equipped with the Donaldson-Witten ...

Simultaneous Bosonic and Fermionic T‐Dualization of the Type II Superstring Theory—Buscher Approach and Double Space Representation

Fortschritte der Physik, Volume 74, Issue 1, January 2026.
Abstract In this article I consider type II superstring in the pure spinor formulation with constant background fields in the context of T‐dualization. First, I prove that bosonic and fermionic T‐dualization commute using already known T‐dual transformation laws for bosonic and fermionic T‐dualization.

Corners and islands in the S-matrix bootstrap of the open superstring

Journal of High Energy Physics
We bootstrap the Veneziano superstring amplitude in 10 dimensions from the bottom-up. Starting with the most general maximally supersymmetric Yang-Mills EFT, we input information about the lowest-lying massive states, which we assume contribute via tree ...

The structure of the exact effective action and the quark confinement in MSSM QCD

, 1999
An expression for the exact (nonperturbative) effective action of $N$=1 supersymmetric gauge theories is proposed, supposing, that all particles except for the gauge bosons are massive.

Dynamical Supersymmetry Breaking and the Linear Multiplet [PDF]

, 1995
We analyze gaugino condensation in the presence of a dilaton and an antisymmetric tensor field, with couplings reminiscent of string theories. The degrees of freedom relevant to a supersymmetric description of the effective theory below the scale of ...
