Loop inflection-point inflation

Understand

A novel inflection-point inflation model is analysed.

• The model considers a massless scalar field, whose self-coupling's running is stabilised by a non-renormalisable operator.
• The running is controlled by a fermion loop.
• We find that successful inflation is possible for a natural value of the Yukawa coupling $y\simeq 4\times 10^{-4}$.
