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

We review the most popular models proposed to explain the anomalous forward-backward asymmetry in t tbar production at the Tevatron. We discuss their viability in view of recent LHC data. We summarise their predictions for charge asymmetries at the LHC.

The solid horizontal line corresponds to the CMS measurement of the charge asymmetry, $A_C = -0.013 ±0.040$ [ref] , minus the SM prediction $A_C^SM = 0.006$, the dashed line representing the $1σ$ experimental uncertainty.
