Towards a string realization of the Dark Dimension via T-folds

Journal of High Energy Physics
In this work, we explore the feasibility of realizing the Dark Dimension Scenario through T-fold compactifications on T 5 × S 1, where the base of the internal space S 1 naturally acts as the requisite mesoscopic extra dimension. Utilizing Scherk-Schwarz

Uncovering quasi-degenerate Kaluza-Klein Electro-Weak gauge bosons with top asymmetries at the LHC

, 2013
By exploiting the correlation between charge and spin polarisation asymmetries in t-tbar, we show that combining the two observables could identify the presence of quasi-degenerate states in a resonant signal at the LHC.

Fermion masses and mixings in the supersymmetric Pati-Salam landscape from Intersecting D6-Branes

Journal of High Energy Physics
Recently, the complete landscape of three-family supersymmetric Pati-Salam models from intersecting D6-branes on a type IIA T 6 / ℤ 2 × ℤ 2 $$ {\mathbbm{T}}^6/\left({\mathbb{Z}}_2\times {\mathbb{Z}}_2\right) $$ orientifold has been enumerated consisting ...

Some phenomenology of intersecting D-brane models

, 2004
We present some phenomenology of a new class of intersecting D-brane models. Soft SUSY breaking terms for these models are calculated in the complex structure (u)-moduli dominant SUSY breaking approach (in type IIA).

Higher derivative corrections to string inflation

Journal of High Energy Physics
We quantitatively estimate the leading higher derivative corrections to N $$ \mathcal{N} $$ = 1 supergravity derived from IIB string compactifications and study how they may affect moduli stabilisation and LVS inflation models.

Taxonomy of infinite distance limits

Journal of High Energy Physics
The Emergent String Conjecture constrains the possible types of light towers in infinite-distance limits in quantum gravity moduli spaces. In this paper, we use these constraints to restrict the geometry of the scalar charge-to-mass vectors ...

Autoencoder-driven clustering of intersecting D-brane models via tadpole charge

Journal of High Energy Physics
We study the well-known type IIA intersecting D-brane models on the T 6 / ℤ 2 × ℤ 2 ′ $$ {T}^6/\left({\mathbb{Z}}_2\times {\mathbb{Z}}_2^{\prime}\right) $$ orientifold via a machine-learning approach.

Self-tracking solutions for asymptotic scalar fields

Journal of High Energy Physics
We explore the dynamics of pure scalar fields rolling on an exponential potential in the absence of any additional background fluid and demonstrate the existence of self-tracking solutions in which the self-perturbations of the scalar field act as an ...

End of the world boundaries for chiral quantum gravity theories

Journal of High Energy Physics
We describe the construction of large classes of explicit string theory backgrounds corresponding to 6d and 4d chiral theories with end of the world boundaries, and describe the strong coupling phenomena involved in gapping the chiral (but non-anomalous)
