Impact of Torsion Space-Time on $t\bar{t}$ observables at Hadron Colliders

TL;DR

This paper investigates how a torsion space-time model influences top quark pair production and asymmetries at hadron colliders, showing it can explain observed anomalies and fit all measured observables.

Contribution

It introduces an effective torsion space-time framework and demonstrates its ability to account for top quark asymmetry anomalies at Tevatron and LHC.

Findings

Torsion space-time can explain the Tevatron forward-backward asymmetry.

An allowed parameter space satisfies all $t\bar{t}$ observables at Tevatron and LHC.

The model provides a consistent explanation for top pair production and asymmetries.

Abstract

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 effect of this model on top pair asymmetries at the Tevatron and the LHC. We find that torsion space-time can explain forward-backward asymmetry according to measured anomaly at Tevatron. We find an allowed region in the parameters space which can satisfy simultaneously all $t\bar{t}$ observables measured at Tevatron and LHC.
