Starting from the effective torsion space-time model, we study its effects onthe top pair production cross section at hadron colliders. We also study theeffect of this model on top pair asymmetries at the Tevatron and the LHC. Wefind that torsion space-time can explain forward-backward asymmetry accordingto measured anomaly at Tevatron. We find an allowed region in the parametersspace which can satisfy simultaneously all $t\bar{t}$ observables measured atTevatron and LHC.
