Complex linear multiplets and local supersymmetry breaking

Journal of High Energy Physics, 2022
We study supersymmetry breaking from a complex linear superfield coupled to 4D N=1 supergravity. The theory has two classically decoupled vacua, one supersymmetric and one with broken and intrinsically non-linear supersymmetry. Depending on the values of

Christ–Lee Model: (Anti‐)chiral Supervariable Approach to BRST Formalism

Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021
We derive the off‐shell nilpotent of order two and absolutely anticommuting Becchi‐Rouet‐Stora‐Tyutin (BRST), anti‐BRST, and (anti‐)co‐BRST symmetry transformations for the Christ–Lee (CL) model in one (0 + 1)‐dimension (1D) of spacetime by exploiting the (anti‐)chiral supervariable approach (ACSA) to BRST formalism where the quantum symmetry (i.e ...

Three-form multiplet and supersymmetry breaking

Journal of High Energy Physics, 2017
Recently, a nilpotent real scalar superfield V was introduced in [1] as a model for the Goldstino. It contains only two independent component fields, the Goldstino and the auxiliary D-field.

Quasicomplex N=2, d=1 Supersymmetric Sigma Models

Symmetry, Integrability and Geometry: Methods and Applications, 2013
We derive and discuss a new type of N=2 supersymmetric quantum mechanical sigma models which appear when the superfield action of the (1,2,1) multiplets is modified by adding an imaginary antisymmetric tensor to the target space metric, thus completing ...

Goldstino Superfields in Supergravity [PDF]

Physics of Particles and Nuclei, 2018
We review two off-shell models for spontaneously broken ${\cal N}=1$ and ${\cal N}=2$ supergravity proposed in arXiv:1702.02423 and arXiv:1707.07390. The ${\cal N}=1$ model makes use of a real scalar superfield subject to three nilpotency conditions.

Functional renormalization group flows of $$\mathcal {N}=1$$ N = 1 supersymmetric abelian gauge model with one chiral and one vector superfield

European Physical Journal C: Particles and Fields, 2023
We apply the functional renormalization group approach to a $$\mathcal {N}=1$$ N = 1 supersymmetric gauge model with one chiral superfield coupled to a vector U(1) superfield.

A superfield constraint for N=2 --> N=0 breaking [PDF]

, 2017
We identify a cubic holomorphic constraint that subtends the total breaking of N=2 supersymmetry in a vector multiplet and exhibit its microscopic origin.

On the origin of constrained superfields

Journal of High Energy Physics, 2016
In this work we analyze constrained superfields in supersymmetry and supergravity. We propose a constraint that, in combination with the constrained goldstino multiplet, consistently removes any selected component from a generic superfield. We also describe its origin, providing the operators whose equations of motion lead to the decoupling of such ...

Generic scalar potentials for inflation in supergravity with a single chiral superfield [PDF]

Journal of High Energy Physics, 2014
A bstractWe propose a large class of supergravity models in terms of a single chiral matter superfield, leading to (almost) arbitrary single-field inflationary scalar potentials similar to the F-term in rigid supersymmetry.
