BICEP2 and the Central Charge of Holographic Inflation

TL;DR

This paper discusses how BICEP2 results imply a specific central charge value for the dual CFT in holographic inflation, linking observational data to theoretical models of the early universe.

Contribution

It identifies the central charge of the dual CFT from BICEP2 data, providing a quantitative bridge between inflationary observations and holographic theory.

Findings

BICEP2 results determine the central charge as C_T=1.2×10^9

Establishes a connection between inflationary data and holographic duality

Supports the holographic inflation model with observational evidence

Abstract

Holographic inflation posits that the inflationary deSitter era of our universe is approximately described by a dual three-dimensional Euclidean CFT living on the spatial slice at the end of inflation. We point out that the BICEP2 results determine the central charge of this putative CFT to be given by $C_T=1.2 \times 10^9$.
