A constrained superfield formalism has been proposed in [10] to analyze the low energy physics related to Goldstinos. We prove that this formalism can be reformulated in the language of standard realization of nonlinear supersymmetry. New relations have been uncovered in the standard realization of nonlinear supersymmetry. 

Nonlinear realization of spontaneously broken N = 1 supersymmetry revisited

This paper revisits the nonlinear realization of spontaneously broken N = 1 supersymmetry. It is shown that the constrained superfield formalism as proposed in [6] can be reinterpreted in the

Nonlinearly realized extended supergravity

We provide a nonlinear realization of supergravity with an arbitrary number of supersymmetries by means of coset construction. The number of gravitino degrees of freedom counts the number of

Complex linear superfield as a model for Goldstino

We propose a Goldstino model formulated in terms of a constrained complex linear superfield. Its comparison to other Goldstino models is given. Couplings to supersymmetric matter and supergravity are

A bound on the superpotential

We prove a general bound on the superpotential in theories with broken supersymmetry and broken R-symmetry, |〈W〉| < $$ \frac{1}{2} $$faF, where fa and F are the R-axion and Goldstino decay constants,

Minimal constrained superfields and the Fayet–Iliopoulos model

This work considers the regime where both gauge symmetry and supersymmetry are spontaneously broken, leaving the goldstino as the only light mode in this sector, and shows in three different ways how the nilpotent goldstinos superfield emerges.

We explain how a single scalar degree of freedom can be obtained from projecting out all the other components of a chiral superfield using simple operators in the microscopic theory. We use the

Tree amplitudes from nonlinear supersymmetries in the Volkov-Akulov theory

The characteristics of tree level scattering amplitudes in theories with nonlinear (super)symmetries were recently proposed by Kallosh to be encoded in a simple way directly from the action, based on

Supersymmetry and its dynamical breaking

This paper reviews the subject of supersymmetry and its breaking. The emphasis is on recent developments in metastable, dynamical supersymmetry breaking, which permit the construction of promising

Non-linear realisations in global and local supersymmetry

The subject of this thesis is the construction and the study of four-dimensional effective theories with spontaneously broken and non-linearly realised global and local supersymmetry. In the first



Nonlinear realization of supersymmetry and superconformal symmetry

Nonlinear realizations describing the spontaneous breakdown of supersymmetry and $R$-symmetry are constructed using the Goldstino and $R$-axion fields. The associated $R$-current, supersymmetry

From Linear SUSY to Constrained Superfields

We present a new formalism for finding the low-energy effective Lagrangian of Goldstinos and other fields. This Lagrangian is written using standard superspace and the superfields are constrained to

A nonlinearly realized supersymmetric action describing the invariant couplings of the Goldstino to matter is constructed using the Akulov-Volkov Lagrangian and a goldstino Goldberger-Treiman relation is established and shown to be satisfied by the effective action.

Linearizing the Volkov-Akulov model

The nonlinear realization of supersymmetry of Volkov and Akulov is related to a constrained linear realization in two and four dimensions.

The non-linear realisation structure of models with spontaneously broken supersymmetry

It is proved that any superfield action with spontaneously broken supersymmetry can be equivalently rewritten in terms of the Volkov-Akulov non-linear realisation quantities. Such a rearrangement is

CORRIGENDUM: General relationship between linear and nonlinear realisations of supersymmetry

The close correspondence between the superfield approach to the supersymmetry and the Volkov-Akulov nonlinear realisation is established. The authors show that any superfield, by certain

Quantum Theory of Fields

To say that this is the best book on the quantum theory of fields is no praise, since to my knowledge it is the only book on this subject. But it is a very good and most useful book. The original was
