Inflation from M-Theory with Fourth-order Corrections and Large Extra Dimensions

TL;DR

This paper explores inflationary solutions within M-theory incorporating fourth-order curvature corrections, proposing a scenario that links early universe inflation, large extra dimensions, and TeV-scale gravity.

Contribution

It introduces new inflationary solutions in M-theory with higher-order corrections, connecting early universe expansion to large extra dimensions and TeV gravity.

Findings

Found three generalized de Sitter solutions with exponential 3-space expansion.

Proposed an inflationary scenario explaining large extra dimensions.

Suggested a connection between inflation e-folds and TeV-scale gravity.

Abstract

We study inflationary solutions in the M-theory. Including the fourth-order curvature correction terms, we find three generalized de Sitter solutions, in which our 3-space expands exponentially. Taking one of the solutions, we propose an inflationary scenario of the early universe. This provides us a natural explanation for large extra dimensions in a brane world, and suggests some connection between the 60 e-folding expansion of inflation and TeV gravity based on the large extra dimensions.
