Degrees of Metastability in Gauge Mediated Supersymmetry Breaking [PDF]

open access: yes, 2011
This thesis consists of an investigation into supersymmetry and its breaking. Emphasis is placed on the question of metastability and the role of non-topological solitons in the hidden sector.

From linear to non-linear SUSY and back again

open access: yesJournal 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.

Axion Black Hole Solution in Non‐Metricity Gravity

open access: yesFortschritte 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-\

FTheoryTools: Advancing Computational Capabilities for F‐Theory Research

open access: yesFortschritte 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.

The Nelson-Seiberg Theorem Generalized with Nonpolynomial Superpotentials

open access: yesAdvances in High Energy Physics, 2020
The Nelson-Seiberg theorem relates R-symmetries to F-term supersymmetry breaking and provides a guiding rule for new physics model building beyond the Standard Model.

Neutrino Magnetic Moment in the Doublet‐Singlet Leptoquark Model

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
The transition magnetic moment for Majorana neutrinos is studied in a simple extension of the Standard Model. This extension incorporates two scalar Leptoquarks S1 and R~2 with quantum numbers 3¯,113,/ and (3, 2, 1/6), respectively. It is found that these Leptoquarks generate a sizable transition magnetic moment, particularly when the quark bottom is ...
