Query: Observable Quantum Loop Effects in the Sky   Expanding on [1], we analyze in detail the single field chaotic inflationary
models plus a cosine modulation term, augmented by a light scalar field with
inflaton dependent oscillatory mass term. We work out in detail the Feynman
diagrams and compute one, two and in general estimate higher loop two and three
point functions in the in-in formulation. We explicitly establish how the
oscillatory mass term can amplify one-loop effects to dominate over the tree as
well as the higher loop contributions. The power spectrum of curvature
perturbations of this model is hence enhanced compared to the simple single
field chaotic model. As a consequence, one can suppress the tensor to scalar
ratio r and have a different expression for scalar spectral tilt and the
running of the tilt, opening the way to reconcile chaotic models with convex
potential and the Planck data. As in monodromy inflation models, we also have a
cosine modulation in the spectral tilt. We also analyze the bispectrum, which
can be dominated by the amplified one-loop effects, yielding a new shape in
non-Gassuianty. We discuss the bounds on parameter space from all available CMB
observables and possible implications for reheating.
