Behaviors of two supersymmetry breaking scales in N $$ \mathcal{N} $$ = 2 supergravity

open access: yesJournal 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.

Twistor--like Formulation of the Supermembrane in D=11 $^*$

open access: yes, 1993
We propose a new formulation of the D=11 supermembrane theory that involves commuting spinors (twistor--like variables) and exhibits a manifest $n$--extended world volume supersymmetry $(1\leq n\leq 8)$.

Foundations of Ghost Stability

open access: yesFortschritte 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.

Spinor Algebras and Extended Superconformal Algebras [PDF]

open access: yes, 2001
We consider supersymmetry algebras in arbitrary spacetime dimension and signature. Minimal and maximal superalgebras are given for single and extended supersymmetry.

A Note on the Local Observability of Uniform Hypergraphs

open access: yesProceedings 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 ...

Towards the complete N=2 superfield Born-Infeld action with partially broken N=4 supersymmetry [PDF]

open access: yes, 2001
We propose a systematic way of constructing $N=2, d=4$ superfield Born-Infeld action with a second nonlinearly realized N=2 supersymmetry. The latter, together with the manifest N=2 supersymmetry, form a central-charge extended $N=4, d=4$ supersymmetry ...

Partial breaking of extended supersymmetry [PDF]

open access: yesPhysics Letters B, 1984
Abstract In this letter we use nonlinear realizations to examine the breaking of N = 2 extended supersymmetry to N = 1. We derive lagrangians and transformation laws for the generalized N = 2 Akulov-Volkov goldstino field. We analyze the ghost states and show that they may be collected into N = 1 supermultiplets.

Double Copy From Tensor Products of Metric BV■‐Algebras

open access: yesFortschritte 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

open access: yesProceedings, 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.

The Akulov-Volkov Lagrangian, Symmetry Currents and Spontaneously Broken Extended Supersymmetry

open access: yes, 2001
A generalization of the Akulov-Volkov effective Lagrangian governing the self interactions of the Nambu-Goldstone fermions associated with spontaneously broken extended supersymmetry as well as their coupling to matter is presented and scrutinized.
