Cosmology with orthogonal nilpotent superfields [PDF]
Physical Review D, 2015 We study the application of a supersymmetric model with two constrained supermultiplets to inflationary cosmology. The first superfield S is a stabilizer chiral superfield satisfying a nilpotency condition of degree 2, S^2=0. The second superfield Phi is

(4,4) superfield supergravity [PDF]
Classical and Quantum Gravity, 1996 We present the N=4 superspace constraints for the two-dimensional (2d) off-shell (4,4) supergravity with the superfield strengths expressed in terms of a (4,4) twisted (scalar) multiplet TM-I, as well as the corresponding component results, in a form ...

Nuclear Physics B, 1998 We present a superfield formulation of the quantization program for theories with first class constraints. An exact operator formulation is given, and we show how to set up a phase-space path integral entirely in terms of superfields. BRST transformations and canonical transformations enter on equal footing, and they allow us to establish a superspace ...

Superfields, Nilpotent Superfields and Superschemes [PDF]
Symmetry, 2020 We interpret superfields in a functorial formalism that explains the properties that are assumed for them in the physical applications. We study the non-trivial relation of scalar superfields with the defining sheaf of the supermanifold of super spacetime.

On the Role of Torsion and Higher Forms in Off‐Shell Supergravity
Fortschritte der Physik, Volume 71, Issue 8-9, September 2023., 2023 Abstract The presence of a nonvanishing totally antisymmetric (super)torsion, equivalent to an axial vector, and higher forms in the “new minimal” and “old minimal” off‐shell formulations of N=1$\mathcal {N}=1$, D=4$D=4$ supergravity is elaborated. The geometric superspace approach and study both the geometric Lagrangian and the off‐shell closure of ...

Fortschritte der Physik, Volume 71, Issue 6-7, July 2023., 2023 Abstract The b ghost, or b operator, used for fixing Siegel gauge in the pure spinor superfield formalism, is a composite operator of negative ghost number, satisfying {q,b}=□$\lbrace q,b\rbrace =\square$, where q is the pure spinor differential (BRST operator). It is traditionally constructed using non‐minimal variables.

Conformal Interactions Between Matter and Higher‐Spin (Super)Fields
Fortschritte der Physik, Volume 71, Issue 1, January 2023., 2023 Abstract In even spacetime dimensions, the interacting bosonic conformal higher‐spin (CHS) theory can be realised as an induced action. The main ingredient in this definition is the model S[φ,h]$\mathcal {S}[\varphi ,h]$ describing a complex scalar field φ coupled to an infinite set of background CHS fields h, with S[φ,h]$\mathcal {S}[\varphi ,h ...

Fortschritte der Physik, Volume 70, Issue 12, December 2022., 2022 Abstract We develop a general formalism to study the three‐point correlation functions of conserved higher‐spin supercurrent multiplets Jα(r)α̇(r)$J_{\alpha (r) \dot{\alpha }(r)}$ in 4D N=1${\cal N}=1$ superconformal theory. All the constraints imposed by N=1${\cal N}=1$ superconformal symmetry on the three‐point function ⟨Jα(r1)α̇(r1)Jβ(r2)β̇(r2)Jγ(r3)
