Reheating and relic gravitational waves as remedies for degeneracies of non-canonical natural inflation

Karam Bahari, Soma Heydari, Kayoomars Karami

Here, a natural non-canonical inflationary model based on a power-law Lagrangian is investigated. We analyze the scalar spectral index $n_{\mathrm{s}}$ and the tensor-to-scalar ratio $r…
