Modeling General Asymptotic Calabi–Yau Periods
Fortschritte der Physik, Volume 73, Issue 7, July 2025.Abstract In the quest to uncovering the fundamental structures that underlie some of the asymptotic Swampland conjectures the authors initiate the general study of asymptotic period vectors of Calabi–Yau manifolds. The strategy is to exploit the constraints imposed by completeness, symmetry, and positivity, which are formalized in asymptotic Hodge ...

Supersymmetry and supergravity models
Journal of Physics G: Nuclear and Particle Physics, 1998 In this paper a review of the present status of supersymmetric (SUSY) and supergravity (SUGRA) models is presented, emphasizing the ambiguities one encounters in constructing a SUSY or SUGRA version of the standard model.

Wrapped NS5-branes, consistent truncations and Inönü-Wigner contractions
Journal of High Energy Physics, 2021 We construct consistent Kaluza-Klein truncations of type IIA supergravity on (i) Σ2 × S 3 and (ii) Σ3 × S 3, where Σ2 = S 2 /Γ, ℝ2 /Γ, or ℍ2 /Γ, and Σ3 = S 3 /Γ, ℝ3 /Γ, or ℍ3 /Γ, with Γ a discrete group of symmetries, corresponding to NS5-branes wrapped ...

Elliptic Models, Type IIB Orientifolds and the Ads/CFT Correspondence [PDF]
, 2000 We analyze the large N supergravity descriptions of the class of type IIB models T-dual to elliptic type IIA brane configurations containing two orientifold 6-planes and up to two NS 5-branes.

D=4, N=2 Supergravity with Abelian electric and magnetic charges [PDF]
, 2004 We discuss the relation between standard N=2 supergravity with translational gauging and N=2 supergravities with scalar-tensor multiplets with massive tensors and Abelian electric charges.

Double Copy From Tensor Products of Metric BV■‐Algebras
Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.Abstract Field theories with kinematic Lie algebras, such as field theories featuring color–kinematics duality, possess an underlying algebraic structure known as BV■‐algebra. If, additionally, matter fields are present, this structure is supplemented by a module for the BV■‐algebra.

Superconformal Symmetry, NMSSM, and Inflation
, 2010 We identify a particularly simple class of supergravity models describing superconformal coupling of matter to supergravity. In these models, which we call the canonical superconformal supergravity (CSS) models, the kinetic terms in the Jordan frame are ...

Alternative Supersymmetric Spectra [PDF]
, 2000 We describe the features of supersymmetric spectra, alternative to and qualitatively different from that of most versions of the MSSM. The spectra are motivated by extensions of the MSSM with an extra U(1)' gauge symmetry, expected in many grand unified ...
