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 ...

Nilpotent chiral superfield in N=2$$ \mathcal{N}=2 $$ supergravity and partial rigid supersymmetry breaking [PDF]
A bstractIn the framework of N=2$$ \mathcal{N}=2 $$ conformal supergravity in four dimensions, we introduce a nilpotent chiral superfield suitable for the description of partial supersymmetry breaking in maximally supersymmetric spacetimes.

Standard model from a supergravity model with a naturally small cosmological constant
Guided by the naturalness criterion for an exponentially small cosmological constant, we present a string theory motivated 4-dimensional N $$ \mathcal{N} $$ = 1 non-linear supergravity model (or its linear version with a nilpotent superfield) with ...

On the effective potential in higher-derivative superfield theories
We study the one-loop quantum corrections for higher-derivative superfield theories, generalizing the approach for calculating the superfield effective potential.

(Anti)chiral Superfield Approach to Nilpotent Symmetries: Self-Dual Chiral Bosonic Theory [PDF]
We exploit the beauty and strength of the symmetry invariant restrictions on the (anti)chiral superfields to derive the Becchi-Rouet-Stora-Tyutin (BRST), anti-BRST, and (anti-)co-BRST symmetry transformations in the case of a two -dimensional (2) self ...

N $$ \mathcal{N} $$ = 2 Liouville SCFT in four dimensions
We construct a Liouville superconformal field theory with eight real supercharges in four dimensions. The Liouville superfield is an N $$ \mathcal{N} $$ = 2 chiral superfield with sixteen bosonic and sixteen fermionic component fields.

On Modifications of the Sp(2) Covariant Superfield Quantization [PDF]
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
