Abstract
An experimental overview of top-pair event asymmetries is reported, focusing on the forward-backward asymmetry, $A_{FB}$, at the Tevatron and the charge asymmetry, $A_{c}$, at the LHC. Comparisons between $A_{FB}$ and $A_{c}$ at different ranges of $m_{t\bar{t}}$ are sensitive to various Beyond the Stand Model (BSM) models.

An overview of the first CP violation measurements using top-pair events is reported from both CMS and ATLAS via two different techniques that have a bright future.

In this $\sqrt{s}=8$ TeV review, all results are compatible with the Standard Model and no BSM models are ruled out. The majority of LHC results are limited in precision by their statistical uncertainty, which hints at exciting opportunities for $\sqrt{s}=13$ TeV future results.
