Physics Letters B, 1994 We present the theory describing supersymmetrical vortices in the curved superspace of the (1,0) supergravity. The action is defined as a (1,0) locally supersymmetric $SU(2)/U(1)$ coset perturbed by the cosmological constant-like term. The perturbation is such that it preserves the integrability of the coset model.

(0, 4) Projective superspaces. Part I. Interacting linear sigma models
Journal of High Energy Physics, 2023 We describe the projective superspace approach to supersymmetric models with off-shell (0, 4) supersymmetry in two dimensions. In addition to the usual superspace coordinates, projective superspace has extra bosonic variables — one doublet for each SU(2)

Navigating collinear superspace [PDF]
Journal of High Energy Physics, 2020 AbstractWe introduce a new set of effective field theory rules for constructing Lagrangians with$$ \mathcal{N} $$N= 1 supersymmetry in collinear superspace. In the standard superspace treatment, superfields are functions of the coordinates$$ \left({x}^{\mu },{\theta}^{\alpha },{\theta}^{\dagger \overset{\cdot }{\alpha }}\right) $$xμθαθ†α⋅, and ...

Physics Letters B, 1997 It is shown that the equations of motion of eleven-dimensional supergravity follow from setting the dimension zero components of the superspace torsion tensor equal to the Dirac matrices. The proof of this assertion is facilitated by the introduction of a connection taking its values in the Lie algebra of $Spin(1,10)\times R^+$.

Quaternionic (super) twistors extensions and general superspaces [PDF]
, 2017 In a attempt to treat a supergravity as a tensor representation, the four-dimensional NN-extended quaternionic superspaces are constructed from the (diffeomorphyc) graded extension of the ordinary Penrose-twistor formulation, performed in a previous work

The quantum chiral Minkowski and conformal superspaces [PDF]
, 2011 We give a quantum deformation of the chiral super Minkowski space in four dimensions as the big cell inside a quantum super Grassmannian. The quantization is performed in such way that the actions of the Poincare and conformal quantum supergroups on the ...

Classical and Quantum Gravity, 2001 A discussion of the AdS/CFT correspondence in IIB is given in a superspace context. The main emphasis is on the properties of SCFT correlators on the boundary which are studied using harmonic superspace techniques. These techniques provide the easiest way of implementing the superconformal Ward identities. The Ward identities, together with analyticity,

Journal of High Energy Physics, 2021 Abstract We consider, at the linearized level, the superspace formulation of lower-dimensional F-theory. In particular, we describe the embedding of 3D Type II super-gravity of the superstring, or 4D, N = 1 supergravity of M-theory, into the corresponding F-theory in full detail, giving the linearized action and gauge ...

Super-Laplacians and their symmetries
Journal of High Energy Physics, 2017 A super-Laplacian is a set of differential operators in superspace whose highestdimensional component is given by the spacetime Laplacian. Symmetries of super-Laplacians are given by linear differential operators of arbitrary finite degree and are ...

Physics Letters B, 2008 We formulate the ten-dimensional super-Yang-Mills theory in a twisted superspace with 8+1 supercharges. Its constraints do not imply the equations of motion and we solve them. As a preliminary step for a complete formulation in a twisted superspace, we give a superspace path-integral formulation of the N=2, d=4 super-Yang-Mills theory without matter ...
