Abstract
In the context of the topcolor-assisted technicolor (TC2) model, we study the productions of the charged top-pion associated with single top, charm or bottom quark in γp collision, which proceed via the subprocesses [Formula: see text], [Formula: see text] and [Formula: see text]. With the electron energy Ee = 50 GeV and photon energy Ep = 7 TeV , we find that the production rates can reach the level of several tens fb for [Formula: see text] production, and hundreds of fb for [Formula: see text] (or [Formula: see text]) productions. So one can expect that enough signals could be produced in the large part of the parameter space. Furthermore, these flavor-changing (FC) productions are extremely suppressed in the standard model (SM). With a large number of events and the clean background, the charged top-pion should be observable at the Large Hadron electron Collider (LHeC) based γp colliders. Thus, such charged top-pion production processes may offer a useful way to test the TC2 model.
