Abstract

In the framework of the topcolor-assisted technicolor (TC2) models, we study the productions of a single top or bottom quark associated with a scalar in \ensuremathγ-p collision, which proceed via the subprocesses c\ensuremathγ\ensuremath→t\ensuremathπ_t⁰, c\ensuremathγ\ensuremath→th_t⁰, and c\ensuremathγ\ensuremath→b\ensuremathπ_t⁺ mediated by the anomalous top or bottom coupling tc\ensuremathπ_t⁰, tch_t⁰, and bc\ensuremathπ_t⁺. These productions, while extremely suppressed in the standard model, are found to be significantly enhanced in the large part of the TC2 parameter space; especially, the production via c\ensuremathγ\ensuremath→b\ensuremathπ⁺ can have a cross section of 100 fb, which may be accessible and allow for a test of the TC2 models.
