A Note on the Local Observability of Uniform Hypergraphs

PAMM, 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 ...

Coset construction of a D-brane gauge field

Nuclear Physics B, 2016
D-branes have a world-volume U(1) gauge field A whose field strength F=dA gives rise to a Born–Infeld term in the D-brane action. Supersymmetry and kappa symmetry transformations of A are traditionally inferred by the requirement that the Born–Infeld ...

N $$ \mathcal{N} $$ -extended D = 4 supergravity, unconventional SUSY and graphene

Journal of High Energy Physics, 2020
We derive a 2+1 dimensional model with unconventional supersymmetry at the boundary of an AdS4 N $$ \mathcal{N} $$ -extended supergravity, generalizing previous results. The (unconventional) extended supersymmetry of the boundary model is instrumental in

Supergraphs extended to broken supersymmetries

Nuclear Physics B, 1985
Abstract Supergraph techniques are generalized to the case of broken supersymmetry. The modified superpropagators for the O'Raifeartaigh model are obtained: they are used for the superspace renormalization and the derivation of the effective potential.

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.

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.

Supercurrents in extended supersymmetry

Nuclear Physics B, 1984
Abstract Using the generalization of Noether's theorem to superspace, spinor superfields in extended superspace are derived that satisfy generalized conservation equations. These spinor superfields are superspace moments involving the superconformal parameters of vector indexed supercurrents as in the unextended case. The vector indexed supercurrents

Partial breaking of extended supersymmetry [PDF]

Physics 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.

Notes on Characterizations of 2d Rational SCFTs: Algebraicity, Mirror Symmetry, and Complex Multiplication

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.

N $$ \mathcal{N} $$ = 2 supersymmetry deformations, electromagnetic duality and Dirac-Born-Infeld actions

Journal of High Energy Physics, 2019
We study the general deformation of N $$ \mathcal{N} $$ = 2 supersymmetry transformations of a vector multiplet that forms a (constant) triplet under the SU(2) R-symmetry corresponding to the magnetic dual of the triplet of the Fayet-Iliopoulos (FI ...
