Radiatively induced breaking of conformal symmetry in a superpotential
Physics Letters B, 2016 Radiatively induced symmetry breaking is considered for a toy model with one scalar and one fermion field unified in a superfield. It is shown that the classical quartic self-interaction of the superfield possesses a quantum infrared singularity ...

Higher Spin BRS Cohomology of Supersymmetric Chiral Matter in D=4
, 1993 We examine the BRS cohomology of chiral matter in $N=1$, $D=4$ supersymmetry to determine a general form of composite superfield operators which can suffer from supersymmetry anomalies.

Moduli induced cogenesis of baryon asymmetry and dark matter
Physics 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,

A toolkit for twisted chiral superfields [PDF]
arXiv, 2019 We calculate the most general terms for arbitrary Lagrangians of twisted chiral superfields in 2D (2,2) supersymmetric theories [1]. The scalar and fermion kinetic terms and interactions are given explicitly. We define a set of twisted superspace coordinates, which allows to obtain Lagrangian terms for generic K\"ahler potential and generic twisted ...

Low-scale SUSY breaking and the (s)goldstino physics
, 2012 For a 4D N=1 supersymmetric model with a low SUSY breaking scale (f) and general Kahler potential K(Phi^i,Phi_j^*) and superpotential W(Phi^i) we study, in an effective theory approach, the relation of the goldstino superfield to the (Ferrara-Zumino ...

Realising mutated hilltop inflation in supergravity
Physics Letters B, 2019 We present N=1 supergravity models of mutated hilltop inflation (MHI) for both large and small field sectors. Models with canonical kinetic terms are developed based on a shift symmetric Kähler potential in inflaton superfield, and with a superpotential ...

Manifest superconformal covariance in six-dimensional (2,0) theory
, 2006 A superconformal generalization of Dirac's formalism for manifest conformal covariance is presented and applied to the free (2,0) tensor multiplet field theory in six dimensions.
