The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v2. Results and the main claim are underlined; .

In this short paper, we present constraints on the Galileon inflationary model from the CMB bispectrum. We employ a principal-component analysis of the independent degrees of freedom constrained by data and apply this to the WMAP 9-year data to constrain the free parameters of the model. A simple Bayesian comparison establishes that support for the Galileon model from bispectrum data is at best weak.

  • Working in the `decoupling' limit where gravitational degrees of freedom can be ignored, it was shown in Ref. [ref] that the action for small fluctuations can be written [equation] The decoupling limit applies when the higher-order terms $3$, $4$ and $5$ are relevant, making Galileon self-interactions stronger than gravitational interactions.
