Circumnavigating collinear superspace

Journal of High Energy Physics, 2020
In this paper, we extend the collinear superspace formalism to include the full range of N $$ \mathcal{N} $$ = 1 supersymmetric interactions. Building on the effective field theory rules developed in a companion paper — Navigating Collinear Superspace [1]

Ghostbusters: unitarity and causality of non-equilibrium effective field theories

Journal of High Energy Physics, 2020
: For a non-equilibrium physical system defined along a closed time path (CTP), a key constraint is the so-called largest time equation, which is a consequence of unitarity and implies causality.

AN OPERATOR ANALYSIS OF A SUPERSYMMETRIC EFFECTIVE THEORY [PDF]

International Journal of Modern Physics A, 1996
An analysis of a SU (2)L× SU (2)R invariant, supersymmetric effective theory is given. The resulting leading and next-to-leading independent invariants are stated in terms of the underlying Killing vectors and Kähler potential. The appendices are devoted to the relationship between this geometrical point of view and the standard unitary matrix ...

Navigating collinear superspace

Journal of High Energy Physics, 2020
We introduce a new set of effective field theory rules for constructing Lagrangians with N $$ \mathcal{N} $$ = 1 supersymmetry in collinear superspace. In the standard superspace treatment, superfields are functions of the coordinates x μ θ α θ † α ⋅ $$ \

Topological couplings in higher derivative extensions of supersymmetric three-form gauge theories

Journal of High Energy Physics, 2019
We consider a topological coupling between a pseudo-scalar field and a 3- form gauge field in N = 1 $$ \mathcal{N}=1 $$ supersymmetric higher derivative 3-form gauge theories in four spacetime dimensions. We show that ghost/tachyon-free higher derivative

Swampland constraints on 5d N $$ \mathcal{N} $$ = 1 supergravity

Journal of High Energy Physics, 2020
We propose Swampland constraints on consistent 5-dimensional N $$ \mathcal{N} $$ = 1 supergravity theories. We focus on a special class of BPS magnetic monopole strings which arise in gravitational theories.

On 1D, N $$ \mathcal{N} $$ = 4 supersymmetric SYK-type models. Part II

Journal of High Energy Physics, 2022
This paper is an extension of our last 1D, N $$ \mathcal{N} $$ = 4 supersymmetric SYK paper [1]. In this paper we introduced the complex linear supermultiplet (CLS), which is “usefully inequivalent” to the chiral supermultiplet.

Effective potentials for a class of supersymmetric theories

Physics Letters B, 1982
Abstract We compute one- and two-loop corrections to the effective potential for a class of models in which supersymmetry is spontaneously broken in an O'Raifeartaigh model.

Interaction of supersymmetric nonlinear sigma models with external higher spin superfields via higher spin supercurrents

Journal of High Energy Physics, 2018
We consider a four dimensional generalized Wess-Zumino model formulated in terms of an arbitrary Kähler potential KΦΦ¯ $$ \mathcal{K}\left(\varPhi, \overline{\varPhi}\right) $$ and an arbitrary chiral superpotential WΦ $$ \mathcal{W}\left(\varPhi \right)
