Abstract

The latest measurements of the asymmetry in the angular distributions of the tt events are reviewed. The measurements of the forward-backward asymmetry A_FB in the pp 1.98 TeV collision at the Tevatron show some tension with the standard model calculation, while results of the measurements of the charge asymmetry A_C in pp collisions at 7 TeV and 8 TeV at the LHC are compatible with standard model prediction.
