Photoproduction of the charged top-pions at the LHeC

Abstract

The top triangle moose $(TTM)$ model, which can be seen as the deconstructed version of the topcolor-assisted technicolor ($TC2$) model, predicts the existence of the charged top-pions ${\pi }_t^{\pm }$ in low energy spectrum. In the context of this model, we consider photoproduction of ${\pi }_t^{\pm }$ via the subprocesses $\gamma b\to t{\pi }_t^{-}$ and $\gamma \bar{b}\to \bar{t}{\pi }_t^{+}$ at the large hadron-electron collider ($LHeC$), in which high energy photon beams are generated by using the Compton backscatting method. We find that, as long as the charged top-pions are not too heavy, they can be abundantly produced via $\gamma b$ collision.
