Foundations of Ghost Stability
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.

Resonant heavy Higgs searches at the HL-LHC
Journal of High Energy Physics, 2019 In this work, we show the importance of searches for heavy resonant scalars (H) and pseudoscalars (A). Taking cue from the present searches, we make projections for searches in an extended scalar sector at the high luminosity run of the Large Hadron ...

Fixed points in supersymmetric extensions of the standard model
European Physical Journal C: Particles and Fields, 2022 We search for weakly interacting fixed points in extensions of the minimally supersymmetric standard model (MSSM). Necessary conditions lead to three distinct classes of anomaly-free extensions involving either new quark singlets, new quark doublets, or ...

Celestial Topology, Symmetry Theories, and Evidence for a NonSUSY D3‐Brane CFT
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract Symmetry Theories (SymThs) provide a flexible framework for analyzing the global categorical symmetries of a D$D$‐dimensional QFTD$\text{QFT}_{D}$ in terms of a (D+1)$(D+1)$‐dimensional bulk system SymThD+1$\text{SymTh}_{D+1}$. In QFTs realized via local string backgrounds, these SymThs naturally arise from dimensional reduction of the linking

IS (Low Energy) SUSY STILL ALIVE?
, 2012 Supersymmetry, a new symmetry that relates bosons and fermions in particle physics, still escapes observation. Search for supersymmetry is one of the main aims of the Large Hadron Collider.

Fast and interpretable support vector classification based on the truncated ANOVA decomposition
GAMM-Mitteilungen, Volume 48, Issue 1, March 2025.Abstract Support vector machines (SVMs) are an important tool for performing classification on scattered data, where one usually has to deal with many data points in high‐dimensional spaces. We propose solving SVMs in primal form using feature maps based on trigonometric functions or wavelets.

Visible GeV ALP from TeV Vector‐Like Leptons
Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Supersymmetric D-term Twin Higgs
Journal of High Energy Physics, 2017 We propose a new type of supersymmetric Twin Higgs model where the SU(4) invariant quartic term is provided by a D-term potential of a new U(1) gauge symmetry.

Journal of High Energy Physics, 2021 The difference between the updated experimental result on the muon anomalous magnetic dipole moment and the corresponding theoretical prediction of the standard model on that is about 4.2 standard deviations. In this work, we calculate the muon anomalous

Double Copy From Tensor Products of Metric BV■‐Algebras
Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.Abstract Field theories with kinematic Lie algebras, such as field theories featuring color–kinematics duality, possess an underlying algebraic structure known as BV■‐algebra. If, additionally, matter fields are present, this structure is supplemented by a module for the BV■‐algebra.
