SUSY-QCD Effect on Top-Charm Associated Production at Linear Collider

TL;DR

This paper investigates how supersymmetric quantum chromodynamics (SUSY-QCD) influences top-charm production at future linear colliders, revealing significantly enhanced cross sections compared to the Standard Model predictions.

Contribution

It provides the first detailed calculation of SUSY-QCD effects on top-charm production at linear colliders, showing potential for observable signals.

Findings

SUSY-QCD can increase the cross section to about 0.1 fb

The enhancement factor over the SM is approximately 10^8

Potential detectability of top-charm events at future colliders

Abstract

We evaluate the contribution of SUSY-QCD to top-charm associated production at next generation linear colliders. Our results show that the production cross section of the process $e^+e^-\to t\bar c{or}\bar t c$ could be as large as 0.1 fb, which is larger than the prediction of the SM by a factor of $10^8$.
