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 ...

On the off-shell formulation of N = 2 supergravity with tensor multiplets

Journal of High Energy Physics, 2018
We revisit the construction of N = 2 superconformal multiplets using rheonomic superspace techniques. We apply the result to the derivation of off-shell Poincaré supersymmetric models where a tensor multiplet couples to gravity and to an arbitrary number

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 ...

Fine-Tuning Constraints on Supergravity Models

, 1999
We discuss fine-tuning constraints on supergravity models. The tightest constraints come from the experimental mass limits on two key particles: the lightest CP even Higgs boson and the gluino. We also include the lightest chargino which is relevant when

Flux quantization on 11-dimensional superspace

Journal of High Energy Physics
Flux quantization of the C-field in 11d supergravity is arguably necessary for the (UV-)completion of the theory, in that it determines the torsion charges carried by small numbers N ≪ ∞ of M-branes.

Stable de Sitter vacua in N=2, D=5 supergravity

, 2005
We find 5D gauged supergravity theories exhibiting stable de Sitter vacua. These are the first examples of stable de Sitter vacua in higher-dimensional (D>4) supergravity.

Seven-Disk Manifold, alpha-attractors and B-modes

, 2016
Cosmological alpha-attractor models in \cN=1 supergravity are based on hyperbolic geometry of a Poincar\'e disk with the radius square {\cal R}^2=3\alpha. The predictions for the B-modes, r\approx 3\alpha {4\over N^2}, depend on moduli space geometry and

Aspects of supersymmetry breaking driven inflation in orbifold models

European Physical Journal C: Particles and Fields
We consider gravitationally induced corrections to inflaton potentials driven by supersymmetry breaking in a five-dimensional supergravity, compactified on a $$ S_1/Z_2 $$ S 1 / Z 2 orbifold. The supersymmetry breaking takes place on the hidden brane and

The N $$ \mathcal{N} $$ = 3 Weyl multiplet in four dimensions

Journal of High Energy Physics, 2019
The main ingredient for local superconformal methods is the multiplet of gauge fields: the Weyl multiplet. We construct the transformations of this multiplet for N $$ \mathcal{N} $$ = 3, D = 4. The construction is based on a supersymmetry truncation from
