On extra forces from large extra dimensions

TL;DR

This paper investigates how fluctuations of a brane in higher-dimensional space induce extra forces on particles, revealing new effects from large extra dimensions and relating 4D and higher-dimensional masses.

Contribution

It introduces a model where brane fluctuations produce three distinct forces, providing new insights into particle dynamics in large extra dimension scenarios.

Findings

Fluctuations generate three different forces on particles.

A relationship between 4D and n-dimensional mass is derived.

Charges associated with extra dimensions influence particle motion.

Abstract

The motion of a classical test particle moving on a 4-dimensional brane embedded in an $n$-dimensional bulk is studied in which the brane is allowed to fluctuate along the extra dimensions. It is shown that these fluctuations produce three different forces acting on the particle, all stemming from the effects of extra dimensions. Interpretations are then offered to describe the origin of these forces and a relationship between the 4 and $n$-dimensional mass of the particle is obtained by introducing charges associated with large extra dimensions.
