Shapes of non-Gaussianity in warm inflation

Sphaleron heating has been recently proposed as a mechanism to realize warm inflation when inflaton is an axion coupled to pure Yang-Mills. As a result of heating, there is a friction coefficient γ ∝ T 3 in the equation of motion for the inflaton, and a thermal contribution to cosmological fluctuati...
