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.

Hidden Sectors from Multiple Line Bundles for the B−L$B-L$ MSSM
Fortschritte der Physik, Volume 70, Issue 7-8, August 2022., 2022 Abstract We give a formalism for constructing hidden sector bundles as extensions of sums of line bundles in heterotic M‐theory. Although this construction is generic, we present it within the context of the specific Schoen threefold that leads to the physically realistic B−L$B-L$ MSSM model.

Who's Afraid of the Supersymmetric Dark? The Standard Model vs Low‐Energy Supergravity
Fortschritte der Physik, Volume 70, Issue 7-8, August 2022., 2022 Abstract Use of supergravity equations in astronomy and late‐universe cosmology is often criticized on three grounds: (i) phenomenological success usually depends on the supergravity form for the scalar potential applying at the relevant energies; (ii$ii$) the low‐energy scalar potential is extremely sensitive to quantum effects involving very massive ...

Representations of Superfields. II [PDF]
Progress of Theoretical Physics, 1997 D. Using these operators, we construct the projection operators which decompose a linear vector superfields into irreducible representations. The forms of the irreducible representations are explicitly described, and the equivalence of the representations under supersymmetric transformations is discussed.

Nilpotent Symmetries of a Model of 2D Diffeomorphism Invariant Theory: BRST Approach
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 Within the framework of the Becchi‐Rouet‐Stora‐Tyutin (BRST) formalism, we discuss the full set of proper BRST and anti‐BRST transformations for a 2D diffeomorphism invariant theory which is described by the Lagrangian density of a standard bosonic string. The above (anti‐)BRST transformations are off‐shell nilpotent and absolutely anticommuting.

Superfield component decompositions and the scan for prepotential supermultiplets in 10D superspaces [PDF]
Journal of High Energy Physics, 2019 The first complete and explicit SO(1,9) Lorentz descriptions of all component fields contained in the N $$ \mathcal{N} $$ = 1, N $$ \mathcal{N} $$ = 2A, and N $$ \mathcal{N} $$ = 2B unconstrained scalar 10D superfields are presented.
