, 2000 It is known that chiral fermions naturally appear at certain intersections of branes at angles. Motivated by this fact, we propose a string scenario in which different standard model gauge interactions propagate on different (intersecting) brane worlds ...

Generalized three-family supersymmetric Pati-Salam models from Type IIA intersecting D6-branes
Journal of High Energy PhysicsGeneralizing three-family chiral fermion conditions to I ac = −(3 + h) and I a c ′ = h $$ {I}_{a{c}^{\prime }}=h $$ , with positive integer h, we extend the landscape of three-family N = 1 $$ \mathcal{N}=1 $$ supersymmetric Pati-Salam models in a broader

Cosmic necklaces in string theory and field theory
, 2010 PhDIn this thesis we investigate astrophysical phenomena which arise in models with compact extra dimensions, focussing on the cosmological consequences of strings which wrap cycles in the internal space. Embedding our strings in the Klebanov-Strassler

GUT and standard-like models in intersecting D-brane worlds [PDF]
, 2006 The main goal of string phenomenology is to find a convincing connection be- tween realistic particle physics and string theory. An extended object called D-brane in string theory is shown as a very powerful tool to resolve phenomenology problems.

Fermion masses and mixings in the supersymmetric Pati-Salam landscape from Intersecting D6-Branes
Journal of High Energy PhysicsRecently, 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 ...

Using the Virasoro conditions to revise the model of a quark-gluon string fragmentation
Journal of High Energy PhysicsQuark-gluon string fragmentation is usually seen as a universal process with its physics remaining unchanged for different colliding systems and center-of-mass energy.

Scale hierarchies and string cosmology
, 2017 International audienceI describe the phenomenology of a model of supersymmetry breaking in the presence of a tiny (tuneable) positive cosmological constant.

Aspects of string phenomenology in particle physics and cosmology [PDF]
, 2016 I discuss possible connections between several scales in particle physics and cosmology, such the the electroweak, inflation, dark energy and Planck scales. In particular, I discuss the physics of extra dimensions and low scale gravity that are motivated
