On Tachyon kinks from the DBI action

, 2003
We consider solitonic solutions of the DBI tachyon effective action for a non-BPS brane in the presence of an electric field. We find that for a constant electric field $\tilde E\le 1$, regular solitons compactified on a circle admit a singular and ...

Using the Virasoro conditions to revise the model of a quark-gluon string fragmentation

Journal of High Energy Physics
Quark-gluon string fragmentation is usually seen as a universal process with its physics remaining unchanged for different colliding systems and center-of-mass energy.

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 ...

An Exceptional Sector for F-theory GUTs

, 2010
D3-branes are often a necessary ingredient in global compactifications of F-theory. In minimal realizations of flavor hierarchies in F-theory GUT models, suitable fluxes are turned on, which in turn attract D3-branes to the Yukawa points.

The cosmological constant and the weak gravity conjecture

Journal of High Energy Physics
We examine the descent via membrane nucleation through a landscape of vacua where the cosmological constant is given by a combination of four-form fluxes.

Higher order corrections to KPV: The nonabelian brane stack perspective

Journal of High Energy Physics
In this work, we study the decay of D 3 ¯ $$ \overline{D3} $$ -branes in the setup of Kachru, Pearson, and Verlinde (KPV) at higher order in α′ from the perspective of a nonabelian D 3 ¯ $$ \overline{D3} $$ -brane stack.

LREE of a dressed Dp-brane with transverse motion in the partially compact spacetime

Journal of High Energy Physics
In the context of the type IIA/IIB superstring theories, we derive the left-right entanglement entropy (LREE) of a BPS Dp-brane with transverse motion in the presence of a U(1) gauge potential and the Kalb-Ramond field in the partially compact spacetime ...

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.
