Axion Black Hole Solution in Non‐Metricity Gravity
Fortschritte der Physik, Volume 74, Issue 2, February 2026.Abstract A static, spherically symmetric black hole solution in symmetric teleparallel (non‐metricity) gravity sourced by an axion field is constructed. Starting from the modified field equations, exact configurations are obtained characterized by the mass M$M$ and an axion–geometry coupling β$\beta$, with temporal metric function A(r)=1−2Mr+βr$A(r)=1-\

FRAMES FOR SUPERSYMMETRY [PDF]
International Journal of Modern Physics A, 2009 We explain how the redefinitions of supermultiplet component fields, comprising what we call "frame shifts," can be used in conjuction with the graphical technology of multiplet Adkinras to render manifest the reducibility of off-shell representations of supersymmetry.

Supersymmetry breaking in 4D string theory
, 1993 In this thesis we address the problem of supersymmetry breaking in four dimensional string theory. We derive an effective Lagrangian describing the low energy degrees of freedom including the Goldstone mode associated with the spontaneously broken R ...

From linear to non-linear SUSY and back again
Journal of High Energy Physics, 2017 We show that couplings of the goldstino field, appearing when global supersymmetry is broken, can always be described in superspace by means of a nilpotent chiral superfield X, satisfying X 2 = 0.

FTheoryTools: Advancing Computational Capabilities for F‐Theory Research
Fortschritte der Physik, Volume 74, Issue 1, January 2026.Abstract A primary goal of string phenomenology is to identify realistic four‐dimensional physics within the landscape of string theory solutions. In F‐theory, such solutions are encoded in the geometry of singular elliptic fibrations, whose study often requires particularly challenging and cumbersome computations.

Nuclear Physics B - Proceedings Supplements, 2003 A method is proposed for latticizing a class of supersymmetric gauge theories, including N=4 super Yang-Mills. The technique is inspired by recent work on ``deconstruction''. Part of the target theory's supersymmetry is realized exactly on the lattice, reducing or eliminating the need for fine tuning.

N=2 central charge superspace and a minimal supergravity multiplet
, 1998 We extend the notion of central charge superspace to the case of local supersymmetry. Gauged central charge transformations are identified as diffeomorphisms on the same footing as spacetime diffeomorphisms and local supersymmetry transformations.

The search for supersymmetry in complex hadronic states using the ATLAS detector
, 2021 The standard model of particle physics is incomplete. A well motivated solution to several of its issues, including the absence of dark matter, is a theoretical extension called supersymmetry.

Supersymmetric Poisson and Poisson-supersymmetric sigma models
Journal of High Energy PhysicsWe revisit and construct new examples of supersymmetric 2D topological sigma models whose target space is a Poisson supermanifold. Inspired by the AKSZ construction of topological field theories, we follow a graded-geometric approach and identify two ...

Harmonic Superfields in N=4 Supersymmetric Quantum Mechanics
Symmetry, Integrability and Geometry: Methods and Applications, 2011 This is a brief survey of applications of the harmonic superspace methods to the models of N=4 supersymmetric quantum mechanics (SQM). The main focus is on a recent progress in constructing SQM models with couplings to the background non-Abelian gauge ...
