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]

On singular effective superpotentials in supersymmetric gauge theories [PDF]
Journal of High Energy Physics, 2006 We study N=1 supersymmetric SU(2) gauge theory in four dimensions with a large number of massless quarks. We argue that effective superpotentials as a function of local gauge-invariant chiral fields should exist for these theories. We show that although the superpotentials are singular, they nevertheless correctly describe the moduli space of vacua ...

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 ⋅ $$ \

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 ...

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.

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)
