Single top quark production through unparticles at photon colliders

TL;DR

This paper explores how unparticles could influence single top quark production in photon-photon collisions, analyzing polarization effects and scaling dimensions to identify potential signatures of unparticle physics.

Contribution

It provides a detailed analysis of unparticle effects on top quark production cross sections in photon collisions, highlighting polarization configurations and scaling dimensions as key factors.

Findings

$(+-)$ polarization is most effective for detecting unparticle signatures

Unparticle effects vary with the scaling dimension $d$ between 1 and 2

Cross section sensitivities depend on polarization and unparticle parameters

Abstract

We investigate the single top quark production with the exchange of unparticles through high energy photon-photon collision $\gamma \gamma\to t \bar c$. The effects of unparticles on the scattering cross sections for different polarization configurations, and for various values of the scaling dimension $d, 1<d<2$ are analysed. It is shown that the $(+-)$ polarisation configuration is more preferable searching for unparticle physics signatures.
