Single top or bottom production associated with a scalar in γ p 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 -> tπt0, cγ -> t ht0 and cγ -> bπ+t mediated by the anomalous top or bottom coupling tcπt0, tcht0 and bcπt+. 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.
