Likelihood analysis of small field polynomial models of inflation yielding a high Tensor-to-Scalar ratio

Inflationary potentials, with Planckian field excursions, described by a 6th degree polynomial are studied. We solve the Mukhanov-Sasaki equations exactly and employ a probabilistic approach as well as multinomial fitting to analyse the results. We identify the most likely models which yield a tenso...
