The Spectrum of Fluctuations in the Cosmic Microwave Background

The position of the first peak à total density ΩTot

The other peaks depend on density of ordinary matter Ωatoms & dark matter ΩDark

First No-Scale Supergravity Model of Inflation

•  No ‘holes’ in effective potential with negative cosmological constant

JE, Enqvist, Nanopoulos, Olive & Srednicki, 1984

•  A no-scale supergravity model of inflation that interpolates between Planck and BICEP2:

•  Identify inflaton with components of modulus T:

•  Effective Lagrangian:
