Higher spins in hyper-superspace

Nuclear Physics B, 2015
We extend the results of arXiv:1401.1645 on the generalized conformal Sp(2n)-structure of infinite multiplets of higher-spin fields, formulated in spaces with extra tensorial directions (hyperspaces), to the description of OSp(1|2n)-invariant infinite ...

Noncommutative Superspace, Supermatrix and Lowest Landau Level

, 2003
By using graded (super) Lie algebras, we can construct noncommutative superspace on curved homogeneous manifolds. In this paper, we take a flat limit to obtain flat noncommutative superspace.

Supersymmetry in noncommutative superspaces [PDF]

, 2003
Non commutative superspaces can be introduced as the Moyal-Weyl quantization of a Poisson bracket for classical superfields. Different deformations are studied corresponding to constant background fields in string theory.

Magnetic structure determination of multiple phases in the multiferroic candidate GdCrO3

Acta Crystallographica Section B, Volume 81, Issue 3, Page 293-301, June 2025.
Using neutron powder diffraction, the successive magnetic structures in multiferroic candidate GdCrO3 have been determined, including a complex incommensurate phase below 2.3 K. The symmetry analysis uses a combination of little group formalism and superspace group approach highlighting the strength of each method and the results are reported using the

Massive on-shell supersymmetric scattering amplitudes

Journal of High Energy Physics, 2019
We introduce a manifestly little group covariant on-shell superspace for massive particles in four dimensions using the massive spinor helicity formalism.

Double-Spinor Superstrings on Coset Superspaces

, 2008
The double-spinor formalism, proposed by Aisaka and Kazama, provides a basis for the pure-spinor formalism, which allows manifestly super-Poincare covariant quantization of superstrings.

Superconformal interpretation of BPS states in AdS geometries [PDF]

, 2000
We carry out a general analysis of the representations of the superconformal algebras SU(2,2/N), OSp(8/4,R) and OSp(8^*/4) and give their realization in superspace.

Non-uniqueness of the supersymmetric extension of the O(3) σ-model

Journal of High Energy Physics, 2017
We study the supersymmetric extensions of the O(3) σ-model in 1+1 and 2+1 dimensions. We show that it is possible to construct non-equivalent supersymmetric versions of a given model sharing the same bosonic sector and free from higher-derivative terms.

Correlation functions of spinor current multiplets in N $$ \mathcal{N} $$ = 1 superconformal theory

Journal of High Energy Physics, 2021
We consider N $$ \mathcal{N} $$ = 1 superconformal field theories in four dimensions possessing an additional conserved spinor current multiplet S α and study three-point functions involving such an operator.
