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

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 $10^8$.
