We propose a charged, electrically neutral, and flavour changing Z' model toconciliate the apparent disagreement between the important excess found in thetop-antitop Tevatron forward-backward asymmetry and the null -compatible withnegative- results found in the LHC charge asymmetry. We show that this modelcontributes positively to the forward-backward asymmetry, whereas naturally anew cancellation is turned on at the LHC, yielding a null, or even negative,charge asymmetry. We found the region in parameter space that is simultaneouslyallowed by the stringent Tevatron and LHC observables. We show that the modelis safe to atomic parity violation constraints and to tj resonance searches,and propose a possible increase in the Z' width to avoid ttj constraints. Weevaluate the constraints to the model, as well as distinctive features in thefore-coming experimental results.
