چکیده
Extended objects, known as ‘branes’, currently play an essential role in our understanding of the non-perturbative dynamics underlying tendimensional (D=10) superstring theories and the 11-dimensional (D=11) M-theory (see [1] for a recent review). In the context of the effective D=10 or D=11 supergravity theory a ‘p-brane’ is a solution of the field equations representing a p-dimensional extended source for an abelian (p + 1)-form gauge potential Ap+1 with (p + 2)form field strength Fp+2. As such, the p-brane carries a charge

Spherically Symmetric Solutions in a New Braneworld Massive Gravity Theory
In this paper, a combination of the braneworld scenario and covariant de Rham-Gabadadze-Tolley (dRGT) massive Gravity theory is proposed. In this setup, the five-dimensional bulk graviton is considered to be massive. The five dimensional nonlinear ghost-free massive gravity theory affects the 3-brane dynamics and the gravitational potential on the brane. Following the solutions with spherical s...
متن کاملThe massive Elko spinor field in the de Sitter braneworld model
The Elko spinor field is a spin 1/2 fermionic quantum field with a mass dimension introduced as a candidate of dark matter. In this work, we study the localization of Elko fields on a de Sitter thick brane constructed by a canonical or phantom scalar field. By presenting the mass-independent potentials of Kaluza-Klein (KK) modes in the corresponding Schrödinger equations, it is shown that the E...
متن کاملBrane Surgery with Thom Classes
We propose a method to investigate the conservation of brane charges at the intersection of two or more branes using the Thom classes of their normal bundles. In particular we find a relation between the charge of the branes involved in the configuration and the charge of the defects on the branes due to the intersection. We also explore the applications of our method for various brane intersec...
متن کاملBrane surgery: energy conditions, traversable wormholes, and voids
Branes are ubiquitous elements of any low-energy limit of string theory. We point out that negative tension branes violate all the standard energy conditions of the higher-dimensional spacetime they are embedded in; this opens the door to very peculiar solutions of the higher-dimensional Einstein equations. Building upon the (3+1)-dimensional implementation of fundamental string theory, we illu...
