A New Angle on Intersecting Branes in Infinite Extra Dimensions
Ann E Nelson
TL;DR
This paper constructs 6-dimensional solutions with intersecting 4-branes that localize gravity to a 3+1 dimensional intersection, expanding understanding of brane configurations in higher-dimensional theories.
Contribution
It introduces new solutions to Einstein's equations with intersecting branes in six dimensions, demonstrating gravity localization under specific tension conditions.
Findings
Gravity is localized to the intersection in the constructed solutions.
Solutions exist for a continuous range of 4-brane tensions.
A condition on intersection tension is necessary for localization.
Abstract
I construct solutions to Einstein's equations in 6 dimensions with bulk cosmological constant and intersecting 4-branes. Solutions exist for a continuous range of 4-brane tension, with long distance gravity localized to a 3+1 dimensional Minkowski intersection, provided that the additional tension of the intersection satisfies one condition.
