Topics on String Phenomenology [PDF]

, 2007
These lectures present some topics of string phenomenology and contain two parts. In the first part, I review the possibility of lowering the string scale in the TeV region, that provides a theoretical framework for solving the mass hierarchy problem and

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.

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 ...

The bubble of nothing under T-duality

Journal of High Energy Physics
The bubble of nothing is a solution to Einstein’s equations where a circle shrinks and pinches off smoothly. As such, it is one of the simplest examples of a dynamical cobordism to nothing.

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

Modular Zeros

Physics Letters B
Modular symmetries are known to be powerful and have various remarkable properties. We point out that the structure of vector-valued modular forms (VVMFs) space leads to the absence of couplings which cannot be explained in terms of the usual symmetries.

Induced gravitational waves from flipped SU(5) superstring theory at nHz

Physics Letters B
The no-scale flipped SU(5) superstring framework constitutes a very promising paradigm for physics below the Planck scale providing us with a very rich cosmological phenomenology in accordance with observations.
