Abstract
Recently it has been shown that measurement of charge asymmetry of top pair production at LHC excludes any flavor violating vector gauge boson that could explain Tevatron forward-backward asymmetry (FBA). We consider the general form of a gauge boson including left-handed, right-handed vector and tensor couplings to examine FBA and charge asymmetry. To evaluate top pair asymmetries at Tevatron and LHC, we consider mixing constraints on flavor changing couplings and show that this model still explain forward-backward asymmetry at Tevatron and charge asymmetry can not exclude it in part of parameters space.
