Conformal invariance and quantum integrability of sigma models on symmetric superspaces
, 2007 We consider two dimensional nonlinear sigma models on few symmetric superspaces, which are supergroup manifolds of coset type. For those spaces where one loop beta function vanishes, two loop beta function is calculated and is shown to be zero. Vanishing

A connection between twistors and superstring sigma models on coset superspaces
, 2019 We consider superstring sigma models that are based on coset superspaces G/H in which H arises as the fixed point set of an order-4 automorphism of G. We show by means of twistor theory that the corresponding first-order system, consisting of the Maurer ...

Topological couplings in higher derivative extensions of supersymmetric three-form gauge theories
Journal of High Energy Physics, 2019 We consider a topological coupling between a pseudo-scalar field and a 3- form gauge field in N = 1 $$ \mathcal{N}=1 $$ supersymmetric higher derivative 3-form gauge theories in four spacetime dimensions. We show that ghost/tachyon-free higher derivative

Cohomological Reduction of Sigma Models [PDF]
, 2010 This article studies some features of quantum field theories with internal supersymmetry, focusing mainly on 2-dimensional non-linear sigma models which take values in a coset superspace.

Journal of High Energy Physics, 2018 We consider a four dimensional generalized Wess-Zumino model formulated in terms of an arbitrary Kähler potential KΦΦ¯ $$ \mathcal{K}\left(\varPhi, \overline{\varPhi}\right) $$ and an arbitrary chiral superpotential WΦ $$ \mathcal{W}\left(\varPhi \right)

What is the geometry of superspace? [PDF]
Physical Review D, 1995 We investigate certain properties of the Wheeler-DeWitt metric (for constant lapse) in canonical General Relativity associated with its non-definite nature. Contribution to the conference on Mach's principle: "From Newtons Bucket to Quantum Gravity", July 26-30 1993, Tuebingen ...

Supersymmetry and T T ¯ $$ T\overline{T} $$ deformations
Journal of High Energy Physics, 2019 We propose a manifestly supersymmetric generalization of the solvable T T ¯ $$ T\overline{T} $$ deformation of two-dimensional field theories. For theories with (1, 1) and (0, 1) supersymmetry, the deformation is defined by adding a term to the ...

HERMITIAN SYMMETRIC SUPERSPACES OF TYPE IV
, 1993 A construction of the Hermitian symmetric superspaces which are the super- manifold analogs of the Cartan domains of type IV is presented herein. Natural generalizations of the Jordan triple product and Bergman operator for the su- perdomains are ...

Covariant differential calculus on SPh2 vertical bar 1
, 2019 The h-deformed symplectic superspaces via a contraction of the q-deformed symplectic superspaces are introduced and a covariant differential calculus on the quantum symplectic superspace SPh2 vertical bar 1 is ...
