T-branes and geometry [PDF]

open access: yesJournal of High Energy Physics, 2014
T-branes are a non-abelian generalization of intersecting branes in which the matrix of normal deformations is nilpotent along some subspace. In this paper we study the geometric remnant of this open string data for six-dimensional F-theory vacua. We show that in the dual M-theory / IIA compactification on a smooth Calabi-Yau threefold X, the geometric

Constraints on cosmologies inside black holes

open access: yesJournal of High Energy Physics, 2022
We study the construction of holographic models with closed FRW cosmologies on the worldvolume of a constant-tension brane inside a Schwarzschild-AdS black hole.

D3-brane loop amplitudes from M5-brane tree amplitudes

open access: yesJournal of High Energy Physics, 2020
We study loop corrections to scattering amplitudes in the world-volume theory of a probe D3-brane, which is described by the supersymmetric Dirac-Born-Infeld theory.

S-BRANES, NEGATIVE TENSION BRANES AND COSMOLOGY [PDF]

open access: yesString Phenomenology, 2003
A general class of solutions of string background equations is studied and its physical interpretations are presented. These solutions correspond to generalizations of the standard black p-brane solutions to surfaces with curvature k=-1,0. The relation with the recently introduced S-branes is provided.

Black strings from minimal geometric deformation in a variable tension brane-world [PDF]

open access: yes, 2013
We study brane-world models with variable brane tension and compute corrections to the horizon of a black string along the extra dimension. The four-dimensional geometry of the black string on the brane is obtained by means of the minimal geometric ...

Discrete flavor symmetries in D-brane models [PDF]

open access: yes, 2013
A bstractWe study the presence of discrete flavor symmetries in D-brane models of particle physics. By analyzing the compact extra dimensions of these models one can determine when such symmetries exist both in the context of intersecting and magnetized ...
