Pair production of charged top-pions in the $\gamma\gamma$ collisions at the ILC

TL;DR

This paper investigates the production of charged top-pions predicted by the TC2 model at future gamma-gamma colliders, showing they could be observable with significant production rates, aiding in testing the model.

Contribution

First detailed analysis of charged top-pion pair production at gamma-gamma colliders within the TC2 framework.

Findings

Production rates can reach hundreds of femtobarns.

Charged top-pions are potentially observable at gamma-gamma colliders.

Results support using collider experiments to test the TC2 model.

Abstract

The top-color assisted technicolor (TC2) mode predicts the existence of a pair of charged top-pions $\pi^{\pm}_t$. In this paper, we study the production of the charged top-pions pair $\pi^{\pm}_t$ at next generation $\gamma\gamma$ colliders. The results show that the production rates can reach the level of $10^2$ fb with reasonable parameter space. With a large number of events and the clean background, the charged top-pion should be observable at the $\gamma\gamma$ colliders. Therefore, our studies can help us to search for charged top-pion, and furthermore, to test the TC2 model.
