Superfield Hamiltonian quantization in terms of quantum antibrackets [PDF]
, 2016 We develop a new version of the superfield Hamiltonian quantization. The main new feature is that the BRST-BFV charge and the gauge fixing Fermion are introduced on equal footing within the sigma model approach, which provides for the actual use of the ...

Standard model from a supergravity model with a naturally small cosmological constant
Journal of High Energy Physics, 2021 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 ...

Effective operators in SUSY, superfield constraints and searches for a UV completion [PDF]
, 2015 A bstractWe discuss the role of a class of higher dimensional operators in 4D N=1 super-symmetric effective theories. The Lagrangian in such theories is an expansion in momenta below the scale of “new physics” (Λ) and contains the effective operators ...

Nilpotent chiral superfield in N=2$$ \mathcal{N}=2 $$ supergravity and partial rigid supersymmetry breaking [PDF]
, 2015 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.

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 ...

Quantum dynamics of $N=1$, $D=4$ supergravity compensator [PDF]
, 1996 A new $N=1$ superfield theory in $D=4$ flat superspace is suggested. It describes dynamics of supergravity compensator and can be considered as a low-energy limit for $N=1$, $D=4$ superfield supergravity.

Gauge-fixing Condition on Prepotential of Chiral Multiplet for Nongeometric Backgrounds
, 2016 We study a supergauge transformation of a complex superfield which generates a chiral superfield in two-dimensional ${\cal N}=(2,2)$ theory. This complex superfield is referred to as the prepotential of the chiral superfield.

Comments on the nilpotent constraint of the goldstino superfield [PDF]
, 2015 Superfield constraints were often used in the past, in particular to describe the Akulov-Volkov action of the goldstino by a superfield formulation with $L=(\Phi^\dagger \Phi)_D + [(f\Phi)_F + h.c.]$ endowed with the nilpotent constraint $\Phi^2=0$ for ...
