Demonstrates effectiveness of 5D assisted inflation

Provides a viable inflationary model without fine-tuning

Abstract

We extend the idea of assisted inflation to the case of power-law potentials and demonstrate the simultaneous resolution of two major problems that plague chaotic inflation. The implementation of the same idea in the framework of a 5-dimensional, scalar field theory leads to a model of chaotic inflation free of fine-tuning.
