Gauged (Super)Conformal Models

Physical Sciences Forum, 2023
Superconformal mechanics describes superparticle dynamics in near-horizon geometries of supersymmetric black holes. We systematically study the minimal compatible set of constraints required for a gauged superconformal symmetry.

Extended supersymmetry with gauged central charge [PDF]

, 1995
Global N=2 supersymmetry in four dimensions with a gauged central charge is formulated in superspace. To find an irreducible representation of supersymmetry for the gauge connections a set of constraints is given.

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.

Nonperturbative unification and extended supersymmetry [PDF]

Physics Letters B, 1989
Abstract We consider the nonperturbative unification scenario proposed by Maiani, Parisi and Petronzio in N =2 supersymmetric extensions of the standard model. Low-energy gauge coupling constants are computed using two-loop renormalization group equations, with a mass spectrum deduced from simple assumptions on the soft terms necessary to break ...

Weak gravity versus scale separation

Journal of High Energy Physics, 2022
We give evidence that fully supersymmetric Anti-de Sitter vacua of extended supergravity with a residual gauge group containing an abelian factor cannot be scale separated as a consequence of the weak gravity conjecture. We prove this for N = 2 and N = 8

Extended supersymmetry and its reduction on a circle with point singularities

, 2005
We investigate $N$-extended supersymmetry in one-dimensional quantum mechanics on a circle with point singularities. For any integer $n$, $N=2n+1$ supercharges are explicitly constructed in terms of discrete transformations, and a class of singularities ...

Homology of Lie algebra of supersymmetries and of super Poincare Lie algebra

, 2011
We study the homology and cohomology groups of super Lie algebra of supersymmetries and of super Poincare Lie algebra in various dimensions. We give complete answers for (non-extended) supersymmetry in all dimensions $\leq 11$.

Pauli-Lubanski, supertwistors, and the superspinning particle

Journal of High Energy Physics, 2017
We present a novel construction of the super-Pauli-Lubanski pseudo-vector for 4D supersymmetry and show how it arises naturally from the spin-shell constraints in the supertwistor formulation of superparticle dynamics.

Supermembrane in D=5: component action [PDF]

, 2013
Based on the connection between partial breaking of global supersymmetry, coset approach, which realized the given pattern of supersymmetry breaking, and the Nambu-Goto actions for the extended objects, we have constructed on-shell component action for N=

Is chiral supersymmetry emanant or emergent?

Journal of High Energy Physics
The extended Majorana Nicolai model is one of the simplest models of supersymmetry realized on a fermionic chain in 1 + 1 dimensions. Within a certain parameter region, the extended theory breaks the supersymmetry spontaneously, but it has a ...
