The N-Tachyon Assisted Inflation

TL;DR

This paper explores how multiple open-string tachyons can collectively drive slow-roll inflation when coupled to gravity, extending previous work on tachyon dynamics in cosmology.

Contribution

It demonstrates that an N-tachyon system can produce assisted slow-roll inflation, providing a novel mechanism for inflation driven by multiple tachyons.

Findings

N-tachyon system induces slow-roll inflation

Coupling to gravity enables inflationary dynamics

Extends previous single-tachyon models

Abstract

In continuation of the papers hep-th/0505012 and hep-th/0508101 we investigate the consequences when $N$ open-string tachyons roll down simultaneously. We demonstrate that the $N$-Tachyon system coupled to gravity does indeed give rise to the assisted slow-roll inflation.
