# Light like segment compactification and braneworlds with dynamical string tension

@article{Guendelman2021LightLS, title={Light like segment compactification and braneworlds with dynamical string tension}, author={Eduardo Guendelman}, journal={The European Physical Journal C}, year={2021} }

There is great interest in the construction of brane worlds, where matter and gravity are forced to be effective only in a lower dimensional surface, the brane . How these could appear as a consequence of string theory is a crucial question and this has been widely discussed. Here we will examine a distinct scenario that appears in dynamical string tension theories and where string tension is positive between two surfaces separated by a short distance and at the two surfaces themselves the…

In this paper we describe the general geometrical framework of brane world constructions in orientifolds of type IIA string theory with D6-branes wrapping 3-cycles in a Calabi-Yau 3-fold. These…

In string theory, the consequences of replacing the measure of integration (-γ)1/2 d2x in the Polyakov action by Φ d2x, where Φ is a density built out of degrees of freedom independent of the metric…

Conformally Invariant Braneworld and the Cosmological Constant

Abstract Recently, a new framework for solving the hierarchy problem has been proposed which does not rely on low energy supersymmetry or technicolor. The gravitational and gauge interactions unite…

A brane world model with intersecting branes

- Physics

Abstract A brane world model is investigated, in which there are many branes that may intersect and self-intersect. One of the branes, being a 3-brane, represents our spacetime, while the other…
