Massive vector multiplet with Dirac-Born-Infeld and new Fayet-Iliopoulos terms in supergravity
Journal of High Energy Physics, 2018 We propose a four-dimensional N = 1 supergravity-based Starobinsky-type inflationary model in terms of a single massive vector multiplet, whose action includes the Dirac-Born-Infeld-type kinetic terms and a generalized (new) Fayet-Iliopoulos-type term ...

Supersymmetric traversable wormholes
Journal of High Energy Physics, 2020 We study traversable wormhole solutions in pure gauged N = 2 supergravity with and without electromagnetic fields, which are locally isometric under SO(2, 1) × SO(1, 1). The model allows for 1/2-BPS wormhole solutions whose corresponding globally defined

Sparticle and Higgs-boson production and detection at CERN LEP II in two supergravity models. [PDF]
Physical Review D, Particles and fields, 1993 We study the most promising signals for supersymmetry at CERN LEP II in the context of two well-motivated supergravity models: (i) the minimal SU(5) supergravity model including the stringent constraints from proton stability and a not too young universe

Interplay Between MW, ΩCDMh2, and (g − 2)μ in Flavor Symmetry–Based Supersymmetric Models
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.We study the phenomenological implications of the minimal supersymmetric standard model (MSSM) augmented by a nonabelian flavor symmetry labeled as sMSSM. Incorporating this flavor symmetry allows for a significant reduction in the original plethora of free parameters present in the MSSM, ultimately reducing them down to just seven in sMSSM.

The two-loop five-particle amplitude in N $$ \mathcal{N} $$ = 8 supergravity
Journal of High Energy Physics, 2019 We compute for the first time the two-loop five-particle amplitude in N $$ \mathcal{N} $$ = 8 supergravity. Starting from the known integrand, we perform an integration-by-parts reduction and express the answer in terms of uniform weight master integrals.

Journal of High Energy Physics, 2021 We show that one can uncover a Dine-Seiberg problem for de Sitter critical points in supergravity theories by utilizing the magnetic weak gravity conjecture.

T‐Symmetry in String Geometry Theory
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.String geometry theory is one of the candidates of nonperturbative formulation of string theory. In this paper, we have shown that dimensionally reduced string geometry theories have what we call T‐symmetry. In the case of the dimensional reduction in space‐like directions, the T‐symmetry transformation gives the T‐dual transformation between the Type ...

Demonic constraints on supergravity models [PDF]
Physics Letters B, 1985 Abstract We consider renormalization group scaling of the CP -violating phases of softly broken supersymmetry. We show that unless A ( M X is real or close to zero, these phases are naturally large in conflict with the experimental bound on the dipole electric moment of the neutron (DEMON) d n .

Towards the construction of multi-centered black holes in AdS
Journal of High Energy Physics, 2022 We find a class of approximate perturbative solutions describing multi-centered BPS black holes in asymptotically AdS4. These black holes are moving coplanarly in a circular orbit with common radius but fixed phase differences, where the radius is ...

On Calabi‐Yau Manifolds at Strong Topological String Coupling
Fortschritte der Physik, Volume 72, Issue 12, December 2024.Abstract It was recently shown that integrating out M2 states on Calabi‐Yau manifolds captures non‐perturbative topological string physics in the free energy. In this note, It has been shown that the resulting expression manifests a certain duality symmetry: the free energy at strong string coupling is equal to the Calabi‐Yau period at weak string ...
