Unparticle physics in top pair signals at the LHC and ILC

TL;DR

This paper investigates how unparticle physics could significantly enhance top quark pair production signals at the LHC and ILC, providing potential observable signatures of new physics beyond the Standard Model.

Contribution

It introduces calculations of top pair production cross sections considering vector, tensor, and scalar unparticles, highlighting their potential to produce detectable signals at colliders.

Findings

Unparticle effects can enhance LHC top pair production signals.

At ILC, unparticle effects could increase cross sections by two orders of magnitude.

Smaller unparticle scale dimensions lead to more pronounced signals.

Abstract

We study the effects of unparticle physics in the pair productions of top quarks at the LHC and ILC. By considering vector, tensor and scalar unparticle operators, as appropriate, we compute the total cross sections for pair production processes depending on scale dimension $d_{\U}$. We find that the existence of unparticles would lead to measurable enhancements on the SM predictions at the LHC. In the case of ILC this may become two orders of magnitude larger than that of SM, for smaller values of $d_\U$, a very striking signal for unparticles.
