Impact of torsion space-time on observables at hadron colliders

Starting from the effective torsion space-time model, we study its effects on the top pair production cross section at hadron colliders. We also study the effects of this model on top pair asymmetries at the Tevatron and LHC. We find that torsion space-time can explain forward-backward asymmetry acc...

Description
Summary:Starting from the effective torsion space-time model, we study its effects on the top pair production cross section at hadron colliders. We also study the effects of this model on top pair asymmetries at the Tevatron and LHC. We find that torsion space-time can explain forward-backward asymmetry according to a measured anomaly at the Tevatron. We find an allowed region in the parameter space which can simultaneously satisfy all observables measured at the Tevatron and LHC.
