Z'tc coupling from D0-D0 mixing

Abstract

We bound the $Z^{\prime }tc$ coupling using the $D^0-\overline{D^0}$ meson mixing system. We obtained such coupling which is less than $5.75\times 10^{-2}$. We have studied the $Z^{\prime }$ boson resonance considering single top production in the $e^{+}{e}^{-}\to Z^{\prime }\to tc$ process. We obtained the number of events which is expected to be less than $10^7$ at the International Linear Collider scenario. We get a branching ratio of the order of $10^{-2}$ for the $Z^{\prime }\to tc$ decay.
