Single top or bottom production associated with a scalar in γp collision as a probe of topcolor-assisted technicolor

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 γ-p collision, which proceed via the subprocesses cγ-> tπ_t^0, cγ-> t h_t^0 and cγ-> bπ^+_t mediated by the anomalous top or bottom coupling tcπ_t^0, tch_t^0 and bcπ_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 cγ-> bπ^+ can have a cross section of 100 fb, which may be accessible and allow for a test of the TC2 models.
