Higher-dimensional black holes: Braneworld stars and Hawking radiation. [PDF]

, 2007
In this thesis two aspects of braneworld models are studied. A new attempt at finding the metric of a braneworld black hole within the second Randall-Sundrum model is explored. Branes containing distributions of perfect fluid are embedded in a variety of

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.

Solving inverse problems of Type IIB flux vacua with conditional generative models

Journal of High Energy Physics
We address the inverse problem in Type IIB flux compactifications of identifying flux vacua with targeted phenomenological properties such as specific superpotential values or tadpole constraints using conditional generative models.

Locality and causality properties of light cone string field theory [PDF]

, 2004
The recent discovery of a new maximally supersymmetric background for the type IIB superstring theory has revived the interest in light cone string field theory.

Uplifts in the penumbra: features of the moduli potential away from infinite-distance boundaries

Journal of High Energy Physics
The construction of meta-stable four-dimensional de Sitter vacua in type IIB string compactifications represents an important question and an ongoing area of work.

End of the world brane networks for infinite distance limits in CY moduli space

Journal of High Energy Physics
Dynamical Cobordism provides a powerful method to probe infinite distance limits in moduli/field spaces parameterized by scalars constrained by generic potentials, employing configurations of codimension-1 end of the world (ETW) branes.

Properties of enhançons in supergravity [PDF]

, 2003
A certain class of naked singularities, related to N = 2 pure super Yang-Mills theory, are resolved in string theory with the enhançon mechanism. We study the properties of the enhançon in supergravity.

Morse-Bott inequalities, topology change and cobordisms to nothing

Journal of High Energy Physics
The Cobordism Conjecture predicts spacetime-ending configurations, such as Bubbles of Nothing (BoN), being commonplace. These correspond to vacuum decays in which the compactification manifold C n $$ {\mathcal{C}}_n $$ shrinks to a point, with the ...

New comments on six-dimensional orientifold vacua with reduced rank and unitarity constraints

Journal of High Energy Physics
We revisit and extend the construction of six-dimensional orientifolds built upon the T 4/ℤ N orbifolds with a non-vanishing Kalb-Ramond background, both in the presence of N $$ \mathcal{N} $$ = (1, 0) supersymmetry and Brane Supersymmetry Breaking, thus
