STRING THEORY: UNRAVELING THE FABRIC OF THE UNIVERSE

open access: yesWorldwide Journal of Physics, 2022
This study presents a comprehensive exploration of string theory as a unifying framework for understanding the fundamental structure of the universe. By modeling particles as one-dimensional strings and examining their vibrational modes, this research ...

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.

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.

Search for direct chargino production in anomaly-mediated supersymmetry breaking models based on a disappearing-track signature in pp collisions at s√=7TeV with the ATLAS detector [PDF]

open access: yes, 2013
A search for direct chargino production in anomaly-mediated supersymmetry breaking scenarios is performed in pp collisions at s√=7TeV using 4.7 fb−1 of data collected with the ATLAS experiment at the LHC.

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 ...

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.

Supersymmetry breaking in 4D string theory [PDF]

open access: yes, 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 ...

Free energy expansions of a conditional GinUE and large deviations of the smallest eigenvalue of the LUE

open access: yesCommunications on Pure and Applied Mathematics, Volume 78, Issue 12, Page 2247-2304, December 2025.
Abstract We consider a planar Coulomb gas ensemble of size N$N$ with the inverse temperature β=2$\beta =2$ and external potential Q(z)=|z|2−2clog|z−a|$Q(z)=|z|^2-2c \log |z-a|$, where c>0$c>0$ and a∈C$a \in \mathbb {C}$. Equivalently, this model can be realised as N$N$ eigenvalues of the complex Ginibre matrix of size (c+1)N×(c+1)N$(c+1) N \times (c+1)

Supersymmetry and dualities [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1996
Duality transformations with respect to rotational isometries relate supersymmetric with non-supersymmetric backgrounds in string theory. We find that non-local world-sheet effects have to be taken into account in order to restore supersymmetry at the string level.
