Nambu-Goldstone explosion under brane perforation

TL;DR

This paper demonstrates that mass impacting a three-brane in a five-dimensional space causes Nambu-Goldstone spherical waves to propagate outward, potentially explaining unanticipated energy release events in brane-world cosmology.

Contribution

It introduces the phenomenon of Nambu-Goldstone wave excitation due to brane perforation by bulk mass, a novel effect in brane-world models.

Findings

Perforation excites spherical Nambu-Goldstone waves.

Waves propagate at the speed of light.

Potential link to unexplained energy releases in cosmology.

Abstract

We show that perforation of the three-brane by mass impinging upon it from the five-dimensional bulk excites Nambu-Goldstone spherical wave propagating outwards with the velocity of light. It is speculated that such an effect can give rise to "`unmotivated" energy release events in the brane-world cosmological models.
