On the finiteness of 6d supergravity Landscape

open access: yesJournal of High Energy Physics
We consider supergravity theories with 8 supercharges in d = 6. We show that all the proposed anomaly free theories with unbounded number of massless modes are restricted to a finite subset and thus argue that there is an upper bound on the number of ...

Integrability of N $$ \mathcal{N} $$ = 1 supersymmetric Ruijsenaars-Schneider three-body system

open access: yesJournal of High Energy Physics, 2023
An N $$ \mathcal{N} $$ = 1 supersymmetric extension of the Ruijsenaars-Schneider three-body model is constructed and its integrability is established. In particular, three functionally independent Grassmann-odd constants of the motion are given and their

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

open access: yesFortschritte 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

open access: yesJournal 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

open access: yesJournal 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 ...

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

open access: yesSciPost 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 ...

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

open access: yesFortschritte 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

open access: yesJournal 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 effective lagrangian of supersymmetric Yang-Mills theory [PDF]

open access: yesPhysics Letters B, 1986
Abstract The one-loop effective action of the supersymmetric Yang-Mills theory in the presence of a covariantly constant Yang-Mills superfield is calculated. This is done with the help of Schwinger's proper time method. The propagator of the Yang-Mills superfield in the presence of a non-vanishing background superfield is derived in a closed form ...
