Integrable models and supersymmetry breaking
Nuclear Physics B, 2021 We elaborate on integrable dynamical systems from scalar–gravity Lagrangians that include the leading dilaton tadpole potentials of broken supersymmetry.

Scale Hierarchies in Particle Physics and Cosmology
EPJ Web of Conferences, 2016 We discuss possible connections between several scales in particle physics andcosmology, such the the electroweak, inflation, dark energy and Planck scales.

Inflation from supersymmetry breaking
European Physical Journal C: Particles and Fields, 2017 We explore the possibility that inflation is driven by supersymmetry breaking with the superpartner of the goldstino (sgoldstino) playing the role of the inflaton.

Inflation from Supersymmetry Breaking
Universe, 2019 I discuss the possibility that inflation is driven by supersymmetry breaking, with the superpartner of the goldstino (sgoldstino) playing the role of the inflaton. Imposing an R-symmetry to satisfy the slow-roll conditions, avoiding the so-called η

Supersymmetry breaking by fluxes
Journal of High Energy Physics, 2018 Type II string theory and M-theory admit flux configurations that break supersymmetry below the Kaluza-Klein scale. These backgrounds play a central role in most models of the string landscape.

Fortschritte der Physik, Volume 74, Issue 3, March 2026.ABSTRACT We propose a manifestly duality‐invariant, Lorentz‐invariant, and local action to describe quantum electrodynamics in the presence of magnetic monopoles that derives from Sen's formalism. By employing field strengths as the dynamical variables, rather than potentials, this formalism resolves longstanding ambiguities in prior frameworks.

Metastable supersymmetry breaking in terms of Peccei–Quinn mechanism
Physics Letters B, 2018 Gauge-mediated supersymmetry breaking at metastable vacuum is reconsidered in terms of the Peccei–Quinn (PQ) mechanism. We suggest that for acceptable μ-value generation, such a class of model should involve messenger mass generation via the PQ-breaking ...

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-\

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.

Neutrino Magnetic Moment in the Doublet‐Singlet Leptoquark Model
Advances 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 ...
