Insights into grand unified theories from current experimental data [PDF]

open access: yes, 2015
In this thesis, we investigate several ways how the structure of a high energy particle physics model constituting a grand unification theory (GUT) in supersymmetry (SUSY) can be inferred from multiple types of information obtained at low energy ...

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

Multi-instantons and supersymmetric SU(N) gauge theories [PDF]

open access: yes, 2002
In this thesis the proposed exact results for low energy effective N = 2 supersymmetric SU(N) Yang-Mills gauge theory coupled to Nf fundamental matter multiplets in four dimensions are considered.

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 (

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.

Currents in supersymmetric field theories [PDF]

open access: yes, 2016
A general formalism to construct and improve supercurrents and source or anomaly superfields in two-derivative N = 1 supersymmetric theories is presented. It includes arbitrary gauge and chiral superfields and a linear superfield coupled to gauge fields.

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 ...
