The top-quark charge asymmetry at the LHC and Tevatron through NNLO QCD and NLO EW

Understand

We provide the most up-to-date predictions for the top-quark charge asymmetry A_C at the LHC with a centre-of-mass energy of 8 TeV.

• Our result is accurate at the NNLO level in the strong interactions and at the complete-NLO level in both the strong and electroweak interactions.
• We present results for the inclusive A_C, several differential asymmetries as well as the P_{T,tt} and M_{tt} cumulative asymmetries.
• Similarly to the Tevatron forward-backward asymmetry A_FB, both NNLO QCD and NLO EW corrections to A_C are found to be significant.
