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

q‐Deformed Glueball Spectrum in AdS/QCD Correspondence
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.This work presents the application of the q‐algebra in the glueball spectrum. This algebra is implemented through Jackson’s derivatives in a Schrödinger‐like equation resulting from the gravity fluctuations around the braneworld scenario in five dimensions.

Aspects of Moduli Stabilization in Type IIB String Theory
Advances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016 We review moduli stabilization in type IIB string theory compactification with fluxes. We focus on KKLT and Large Volume Scenario (LVS). We show that the predicted soft SUSY breaking terms in KKLT model are not phenomenological viable. In LVS, the following result for scalar mass, gaugino mass, and trilinear term is obtained: m0 = m1/2 = −A0 = m3/2 ...

Uplift and towers of states in warped throat
Journal of High Energy Physics, 2023 We investigate the connection between the distance conjecture and the uplift potential. For this purpose, we consider the concrete model, the warped deformed conifold embedded into Type IIB flux compactifications, with the uplift potential produced by D ...

Heterotic Braneworld Gravity [PDF]
, 2009 In the past decade, there has been considerable interest in braneworld scenarios where the universe lives on a brane in a higher-dimensional bulk and gravity is modified.

Braneworld black holes and black strings [PDF]
, 2008 This thesis involves the study of strong and weak gravity phenomenology within the braneworld paradigm. We begin with a general overview of the hypothesised concept of extra spatial dimensions and explain why they are so interesting.

Journal of High Energy PhysicsIn Quantum Gravity (QG), large moduli field values lead to towers of exponentially light states, making the QG cut-off field-dependent. In 4D supersymmetric (SUSY) theories, this cut-off is set by the species scale Λ z i z ¯ i $$ \Lambda \left({z}_i ...

Branes vs. GUTS: challenges for string inspired phenomenology
, 2006 This paper studies the compatibility of having a grand unification scheme for particle physics, while at the same time having a perturbative string theory description of such a scheme on a D-brane. This is studied in a model independent approach and finds a negative result. Some additional observations related to model building on branes are made.

braneworld cosmology and holography [PDF]
, 2002 This thesis is devoted to studying two important aspects of braneworld physics: their cosmology and their holography. We examine the Einstein equations induced on a general (n - 2)-brane of arbitrary tension, embedded in some n-dimensional bulk.
