Goldstino and sgoldstino in microscopic models and the constrained superfields formalism

open access: yes, 2011
We examine the exact relation between the superconformal symmetry breaking chiral superfield (X) and the goldstino superfield in microscopic models of an arbitrary Kahler potential (K) and in the presence of matter fields.

FEYNMAN RULES FOR SUPERFIELDS

open access: yesNuclear Physics B, 1975
Abstract The notion of functional differentiation with respect to superfields is defined and used to set up formal rules for computing Green functions and scattering amplitudes in supersymmetric models.

Some aspects of N = 1 SYM renormalization

open access: yesEPJ Web of Conferences, 2016
Using the BRST invariant version of the higher covariant derivative regularization, we demonstrate that in N = 1 supersymmetric gauge theories the three-point vertices with two ghost legs and a single leg of the quantum gauge superfield are finite in all

N=4 supersymmetric d = 1 sigma models on group manifolds

open access: yesNuclear Physics B, 2019
We construct manifestly N=4 supersymmetric off-shell superfield actions for the HKT d=1 sigma models on the group manifolds U(2) and SU(3), using the harmonic d=1 approach. The underlying (4,4,0) and (4,4,0)⊕(4,4,0) multiplets are described, respectively,

Absolutely anticommuting (anti-)BRST symmetry transformations for topologically massive Abelian gauge theory

open access: yes, 2010
We demonstrate the existence of the nilpotent and absolutely anticommuting Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST symmetry transformations for the four (3 + 1)-dimensional (4D) topologically massive Abelian U(1) gauge theory that is described by ...

Inflation in supergravity with a single chiral superfield

open access: yesPhysics Letters B, 2014
We propose new supergravity models describing chaotic Linde- and Starobinsky-like inflation in terms of a single chiral superfield. The key ideas to obtain a positive vacuum energy during large field inflation are (i) stabilization of the real or ...

Moduli induced cogenesis of baryon asymmetry and dark matter

open access: yesPhysics Letters B, 2016
We study a cogenesis mechanism in which the observed baryon asymmetry of the universe and the dark matter abundance can be produced simultaneously at low reheating temperature without violating baryon number in the fundamental interactions. In particular,
