Confrontation of Double-Inflationary Models with Observations

P. Peter, D. Polarski, A. A. Starobinsky

We consider double-inflationary models with two noninteracting scalar fields, a light scalar field ${\varphi }_l$ with potential $\frac{1}{2}{m}_l^2{\varphi }_l^2$ and a heavy scalar field ${\varphi }_h$ with…
