Augmented Superfield Approach to Nilpotent Symmetries of the Modified Version of 2D Proca Theory [PDF]
Advances in High Energy Physics, 2015 We derive the complete set of off-shell nilpotent and absolutely anticommuting Becchi-Rouet-Stora-Tyutin (BRST), anti-BRST, and (anti-)co-BRST symmetry transformations for all the fields of the modified version of two (1+1)-dimensional (2D) Proca theory ...

Superfield theories on $S^3$ and their localization [PDF]
, 2014 We consider the superfield formulation of supersymmetric gauge and matter field theories on a three-dimensional sphere with rigid ${\cal N}=2$ supersymmetry, as well as with ${\cal N}> 2$.

Unconstrained off-shell superfield formulation of 4D, $$ \mathcal{N} $$ = 2 supersymmetric higher spins [PDF]
Journal of High Energy Physics, 2021 We present, for the first time, the complete off-shell 4D,$$ \mathcal{N} $$ N = 2 superfield actions for any free massless integer spin s ≥ 2 fields, using the $$ \mathcal{N} $$ N = 2 ...

Minimal Starobinsky supergravity coupled to a dilaton-axion superfield [PDF]
Physical Review D, 2020 The minimal Starobinsky supergravity with inflaton (scalaron) and goldstino in a massive vector supermultiplet is coupled to the dilaton-axion chiral superfield with the no-scale Kahler potential and a superpotential.

Unimodular vs nilpotent superfield approach to pure dS supergravity [PDF]
Journal of High Energy Physics, 2020 Recent progress in understanding de Sitter spacetime in supergravity and string theory has led to the development of a four dimensional supergravity with spontaneously broken supersymmetry allowing for de Sitter vacua, also called de Sitter supergravity.

On a structure of the one-loop divergences in 4D harmonic superspace sigma-model
European Physical Journal C: Particles and Fields, 2022 We study the quantum structure of four-dimensional $${{\mathcal {N}}}=2$$ N = 2 superfield sigma-model formulated in harmonic superspace in terms of the omega-hypermultiplet superfield $$\omega $$ ω .

Primordial black hole production in inflationary models of supergravity with a single chiral superfield [PDF]
Physical Review D, 2018 We propose a double inflection point inflationary model in supergravity with a single chiral superfield. Such a model allows for the generation of primordial black holes(PBHs) at small scales, which can account for a significant fraction of dark matter ...

Journal of High Energy Physics, 2020 For the first time in the physics literature, the Lorentz representations of all 2,147,483,648 bosonic degrees of freedom and 2,147,483,648 fermionic degrees of freedom in an unconstrained eleven dimensional scalar superfield are presented.

de Sitter Vacua with a Nilpotent Superfield [PDF]
Fortschritte der Physik, 2018 We study the arguments given in [ ] which suggest that the uplifting procedure in the KKLT construction is not valid. First we show that the modification of the SUSY breaking sector of the nilpotent superfield, as proposed in [ ], is not consistent with ...

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.
