ON QUANTUM MODEL OF SUPERGRAVITY COMPENSATOR [PDF]
Modern Physics Letters A, 1996 A new N=1 superfield model in D=4 flat superspace is suggested. This model describes dynamics of chiral compensator and can be treated as a low-energy limit of D=4, N=1 quantum superfield supergravity. Renormalization structure of this model is studied and one-loop counterterms are calculated. It is shown that the theory is infrared-free. An effective

Glueball Mass Spectra and Other Issues for Supergravity Duals of QCD Models [PDF]
, 1998 We derive WKB expressions for glueball masses of various finite temperature supergravity models. The results are very close to recent numerical computations.

Enriques and octonionic magic supergravity models [PDF]
Journal of High Energy Physics, 2008 We reconsider the Enriques Calabi Yau (FHSV) model and its string derivation and argue that the Octonionic magic supergravity theory admits a string interpretation closely related to the Enriques model. The uplift to D=6 of the Octonionic magic model has 16 abelian vectors related to the rank of Type I and Heterotic strings.

Quintessence with two energy scales [PDF]
, 2001 We study quintessence models using low energy supergravity inspired from string theory. We consider effective supergravity with two scales m_S, the string scale, and m_PL, the Planck scale and show that quintessence naturally arises from a supersymmetry ...

, 1993 Theoretical and experimental motivations behind supergravity grand unified models are described. The basic ideas of supergravity, and the origin of the soft breaking terms are reviewed. Effects of GUT thresholds and predictions arising from models possessing proton decay are discussed.

Five-dimensional Superfield Supergravity [PDF]
, 2001 We present a projective superspace formulation for matter-coupled simple supergravity in five dimensions. Our starting point is the superspace realization for the minimal supergravity multiplet proposed by Howe in 1981.

Probing supergravity models with indirect experimental signatures [PDF]
Physical Review D, 1995 We explore the one-loop electroweak radiative corrections in the context of the traditional minimal $SU(5)$ and the string-inspired $SU(5)\times U(1)$ supergravity models by calculating explicitly vacuum-polarization and vertex-correction contributions to the $ _1$ and $ _b$ parameters.

From Minkowski to de Sitter in multifield no-scale models
Journal of High Energy Physics, 2019 We show the uniqueness of superpotentials leading to Minkowski vacua of single-field no-scale supergravity models, and the construction of dS/AdS solutions using pairs of these single-field Minkowski superpotentials.

Non-abelian fermionic T-duality in supergravity
Journal of High Energy Physics, 2021 Field transformation rules of the standard fermionic T-duality require fermionic isometries to anticommute, which leads to complexification of the Killing spinors and results in complex valued dual backgrounds.
