Superconformal Symmetry, The Supercurrent And Non-BPS Brane Dynamics [PDF]
, 2004 The Noether currents associated with the non-linearly realized super-Poincare' symmetries of the Green-Schwarz (Nambu-Goto-Akulov-Volkov) action for a non-BPS p=2 brane embedded in a N=1, D=4 target superspace are constructed. The R symmetry current, the

Extended supersymmetry and the vacuum
Physics Letters B, 1983 Abstract Using light-cone superspace techniques and the adiabatic formalism, we show that the level shift between the bare and the physical vacua is zero order by order in perturbation theory in theories exhibiting extended supersymmetry.

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.

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.

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

Perturbative QCD utilizing extended supersymmetry
Physics Letters B, 1985 We use N = 2 extended supersymmetry to dramatically simplify the diagrammatic calculations of perturbative QCD. The production, by gluon-gluon fusion, of two gluons, three gluons, and two massless gluinos plus a gluon are used as examples.

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.

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 ...

All partial breakings in N=2 $$ \mathcal{N}=2 $$ supergravity with a single hypermultiplet
Journal of High Energy Physics, 2018 We consider partial supersymmetry breaking in N=2 $$ \mathcal{N}=2 $$ supergravity coupled to a single vector and a single hypermultiplet. This breaking pattern is in principle possible if the quaternion-Kähler space of the hypermultiplet admits (at ...
