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.

Supersymmetry and the Spontaneous Breakdown of PT Symmetry [PDF]
, 2001 The appearances of complex eigenvalues in the spectra of PT-symmetric quantum mechanical systems are usually associated with a spontaneous breaking of PT.

Behaviors of two supersymmetry breaking scales in N $$ \mathcal{N} $$ = 2 supergravity
Journal of High Energy Physics, 2019 We study the supersymmetry breaking patterns in four-dimensional N $$ \mathcal{N} $$ = 2 gauged supergravity. The model contains multiple (Abelian) vector multiplets and a single hypermultiplet which parametrizes SO(4, 1)/SO(4) coset.

A Note on the Local Observability of Uniform Hypergraphs
Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 1, March 2025.ABSTRACT Hypergraphs generalize graphs in such a way that edges may connect any number of nodes. If all edges are adjacent to the same number of nodes, the hypergraph is called uniform. Thus, a graph is a 2‐uniform hypergraph. Each uniform hypergraph can be identified with an autonomous dynamical state‐space system, whose vector field is composed of ...

Extended supersymmetry in the space-time R×S3
, 1990 Following recent work on N=1 rigid supersymmetry in the curved space S3, models with extended supersymmetry are examined. Unusual superalgebras with N=2 and N=3 appear.

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.

Predicting Alignment in a Two Higgs Doublet Model
Proceedings, 2019 We show that a non-abelian global S U ( 2 ) R R-symmetry acting on the quartic part of the two Higgs Doublet Model leads, at tree-level, to an automatic alignment without decoupling.

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.Abstract S. Gukov and C. Vafa proposed a characterization of rational N=(1,1)$N=(1,1)$ superconformal field theories (SCFTs) in 1+1$1+1$ dimensions with Ricci‐flat Kähler target spaces in terms of the Hodge structure of the target space, extending an earlier observation by G. Moore.

Interpreting light scalar excesses and heavy scalar cascades in the μ-term extended NMSSM
Journal of High Energy PhysicsThe hints for a scalar resonance near 95 GeV in the LEP b b ¯ $$ b\overline{b} $$ channel and in the LHC diphoton searches remain among the most persistent small deviations in the Higgs sector.

Flavor in SU(5)$SU(5)$ Finite Grand Unified Models
Fortschritte der Physik, Volume 72, Issue 12, December 2024.Abstract Four SU(5)N=1$SU(5) \nobreakspace N=1$ supersymmetric models which exhibit S3$S_3$ and/or ZN$Z_N$ symmetries are studied, that are finite to two or all loops, and their corresponding mass matrices. The first is an all‐loop finite model based on an S3×Z3×Z2$S_3\times Z_3\times Z_2$ flavor symmetry, which leads to phenomenologically nonviable ...
