N=1 superfield description of vector-tensor couplings in six dimensions [PDF]
, 2015 We express supersymmetric couplings among the vector and the tensor multiplets in six dimensions (6D) in terms of N=1 superfields. The superfield description is derived from the invariant action in the projective superspace.

Single-superfield helical-phase inflation
Physics Letters B, 2016 Large-field inflation in supergravity requires the approximate global symmetry needed to protect flatness of the scalar potential. In helical-phase inflation, the U(1) symmetry of the Kähler potential is assumed, the phase part of the complex scalar of a

On Modifications of the Sp(2) Covariant Superfield Quantization [PDF]
, 2003 We propose a modification of the Sp(2) covariant superfield quantization to realize a superalgebra of generating operators isomorphic to the massless limit of the corresponding superalgebra of the osp(1,2) covariant formalism. The modified scheme ensures

Integer superspin supercurrents of matter supermultiplets
Journal of High Energy Physics, 2019 In recent papers [18, 21] we demonstrated that consistent and non-trivial linear transformations of matter supermultiplets generate half-integer superspin supercurrents and the cubic interactions between matter and half-integer superspin supermultiplets.

On Superfield Covariant Quantization in General Coordinates [PDF]
, 2004 We propose a natural extension of the BRST-antiBRST superfield covariant scheme in general coordinates. Thus, the coordinate dependence of the basic scalar and tensor fields of the formalism is extended from the base supermanifold to the complete set of ...

Journal of High Energy Physics, 2018 We present a class of supergravity α-attractors with an approximate global U(1) symmetry corresponding to the axion direction. We also develop a multi-field generalization of these models and show that the α-attractor models with U(1) symmetries have a ...

Goldstino Superfields in Supergravity [PDF]
Physics of Particles and Nuclei, 2018 We review two off-shell models for spontaneously broken ${\cal N}=1$ and ${\cal N}=2$ supergravity proposed in arXiv:1702.02423 and arXiv:1707.07390. The ${\cal N}=1$ model makes use of a real scalar superfield subject to three nilpotency conditions.

A note on gravitational particle production in supergravity
Physics Letters B, 2019 It is pointed out that the gravitational particle production rate of a scalar component of a chiral superfield in supergravity with minimal Kähler potential can be significantly suppressed compared with a minimal scalar field in non-supersymmetric ...

Renormalization in General Gauge Mediation
, 2010 We revisit General Gauge Mediation (GGM) in light of the supersymmetric (linear) sigma model by utilizing the current superfield. The current superfield in the GGM is identified with supersymmetric extension of the vector symmetry current of the sigma ...

Unidexterously constrained worldsheet superfields [PDF]
Journal of Physics A: Mathematical and Theoretical, 2010 Super-constrained superfields have provided for most of the best-known and oft-used representations of supersymmetry. The abelian nature of the Lorentz symmetry on the worldsheet turns out to continue permitting the discovery of new representations, long after the discovery of twisted chiral superfields.
