Inflationary paradigm in trouble after Planck2013
https://arxiv.org/abs/1304.2785

Recent results from the Planck satellite combined with earlier observations from WMAP, ACT, SPT and other
experiments eliminate a wide spectrum of more complex inflationary models and favor models with a single
scalar field, as reported by the Planck Collaboration. More important, though, is that all the simplest inflaton
models are disfavored statistically relative to those with plateau-like potentials. We discuss how a restriction to
plateau-like models has three independent serious drawbacks: it exacerbates both the initial conditions problem
and the multiverse-unpredictability problem and it creates a new difficulty that we call the inflationary
"unlikeliness problem." Finally, we comment on problems reconciling inflation with a standard model Higgs,
as suggested by recent LHC results. In sum, we find that recent experimental data disfavors all the best-motivated
inflationary scenarios and introduces new, serious difficulties that cut to the core of the inflationary paradigm.
Forthcoming searches for B-modes, non-Gaussianity and new particles should be decisive.
