Supersymmetric dS4 solutions in D = 11 supergravity

open access: yesJournal of High Energy Physics, 2022
The necessary and sufficient conditions for warped product dS4 solutions in D = 11 supergravity to be supersymmetric are determined. The Killing spinor is associated with two possible stabilizer groups, SU(3) and G2.

Constraining supergravity models from gluino production

open access: yesNuclear Physics B, 1988
The branching ratios for gluino decays g→qqχ, g→gχ into a stable undetected neutralino are computed as functions of the relevant parameters of the underlying supergravity theory. A simple way of constraining supergravity models from gluino production emerges.

Cosmological constraints on supergravity models [PDF]

open access: yesPhysics Letters B, 1985
Abstract We delineate the domain of supersymmetry breaking parameters in minimal supergravity models for which the cosmological relic photino density is no larger than the closure density. Demanding that the relic density equal the closure density as suggested by inflationary cosmology suggests m q ∼ 42 GeV + 0.89 m g ...

Simultaneous Bosonic and Fermionic T‐Dualization of the Type II Superstring Theory—Buscher Approach and Double Space Representation

open access: yesFortschritte der Physik, Volume 74, Issue 1, January 2026.
Abstract In this article I consider type II superstring in the pure spinor formulation with constant background fields in the context of T‐dualization. First, I prove that bosonic and fermionic T‐dualization commute using already known T‐dual transformation laws for bosonic and fermionic T‐dualization.

Dilaton, moduli and string/five-brane duality as seen from four dimensions [PDF]

open access: yes, 1993
A naive dimensional reduction of the $N=1, D=10$ supergravity theory that naturally arises in five-brane models is used to determine the r\^ole of two fields which are basic ingredients of string models: the dilaton and, among the moduli, the breathing ...

Swampland conjectures for type IIB orientifolds with closed-string U(1)s

open access: yesJournal of High Energy Physics, 2020
We study the weak gravity conjecture, the swampland distance conjecture and the emergence proposal for N $$ \mathcal{N} $$ = 1 orientifold compactifications of type IIB string theory with O3-/O7-planes. We allow for orientifold projections with h + 2 , 1

On the paper “Bundle gerbes” by Michael Murray

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract The article gives a brief survey of Murray's notion of bundle gerbes as introduced in his 1996 paper published in the Journal of the London Mathematical Society, together with some of its applications.

Higher derivative couplings and massive supergravity in three dimensions

open access: yes, 2015
We develop geometric superspace settings to construct arbitrary higher derivative couplings (including R^n terms) in three-dimensional supergravity theories with N=1,2,3 by realising them as conformal supergravity coupled to certain compensators. For all

D-term chaotic inflation in supergravity [PDF]

open access: yes, 2007
Even though the chaotic inflation is one of the most popular inflation models for its simple dynamics and compelling resolutions to the initial condition problems, its realization in supergravity has been considered a challenging task. We discuss how the

Super throats with non trivial scalars

open access: yesJournal of High Energy Physics, 2020
We find new BPS solutions in N = 2 D = 4 Fayet-Iliopoulos gauged super- gravity with STU prepotential. These are stationary solutions carrying a Kerr-Newman throat spacetime geometry and are everywhere regular.
