### Description

We present measurements of the integrated forward-backward charge asymmetry in $t\bar{t}$ production in $p\bar{p}$ collisions using data collected with the D0 detector at the Fermilab Tevatron collider, using both the lepton+jets and dilepton final states. We present the raw measurement as well as results obtained after correcting for acceptance and detector effects and present also measurements as a function of invariant mass of the $t\bar{t}$ pair. We also investigate the dependence of the asymmetry on the total transverse momentum of the $t\bar{t}$ pair.
