Effective action of softly broken supersymmetric theories [PDF]
Physical Review D, 2007 We study the renormalization of (softly) broken supersymmetric theories at the one loop level in detail. We perform this analysis in a superspace approach in which the supersymmetry breaking interactions are parameterized using spurion insertions. We comment on the uniqueness of this parameterization.

Journal of High Energy Physics, 2021 We introduce a first order description of linearized non-minimal (n = −1) supergravity in superspace, using the unconstrained prepotential superfield instead of the conventionally constrained super one forms.

Counting operators in N = 1 supersymmetric gauge theories
Journal of High Energy Physics, 2023 Following a recent publication, in this paper we count the number of independent operators at arbitrary mass dimension in N = 1 supersymmetric gauge theories and derive their field and derivative content.

Exploring the strong-coupling region of SU(N) Seiberg-Witten theory
Journal of High Energy Physics, 2022 We consider the Seiberg-Witten solution of pure N $$ \mathcal{N} $$ = 2 gauge theory in four dimensions, with gauge group SU(N). A simple exact series expansion for the dependence of the 2(N − 1) Seiberg-Witten periods a I (u), a DI (u) on the N − 1 ...

Supersymmetric small-field inflation with tribrid superpotentials [PDF]
, 2016 In this thesis, we study supersymmetric models of tribrid inflation and new inflation, both of which can be realized with a tribrid superpotential. In the first part, we focus on tribrid inflation, deriving relations between cosmological observables ...

Instanton effects in supersymmetric gauge theories [PDF]
Nuclear Physics B, 1985 Abstract We investigate how in supersymmetric gauge theories non-perturbative effects are able to generate non-trivial vacuum properties otherwise forbidden by perturbative non-renormalization theorems. This conclusion can be reliably drawn since the constancy of certain Green functions — due to supersymmetry (SUSY) — allows one to connect vacuum ...

Spin supplementary condition in quantum field theory: covariant SSC and physical state projection
Journal of High Energy Physics, 2023 The spin supplementary conditions are constraints on spin degrees of freedom in classical relativity which restricts physical degrees of freedom to rotations.

Ghost-free vector superfield actions in supersymmetric higher-derivative theories
Journal of High Energy Physics, 2017 We systematically construct ghost-free higher-derivative actions of Abelian vector supermultiplets in four-dimensional N = 1 $$ \mathcal{N}=1 $$ global supersymmetric theories.
