Single vector-like top partner production in the Left-Right Twin Higgs model at TeV energy $e\gamma$ colliders

Understand

The left-right twin Higgs model contains a new vector-like heavy top quark, which mixes with the SM-like top quark.

• In this work, we studied the single vector-like top partner production via process $e^{-}\gamma \rightarrow \nu_{e}\bar{T}b$ at the International Linear Collider.
• We calculated the production cross section at tree level and displayed the relevant differential distributions.
• The result shows that there will be 125 events produced each year with $\sqrt{s}$=2TeV and the integrated luminosity $\mathcal L_{int}\simeq 500fb^{-1}$, and the b-quark tagging and the relevant missing energy $\met$ cut will be helpful to detect this new effect.
