摘要

In the framework of the topcolor-assisted technicolor (TC2) model we investigate the flavor-changing neutral-current production pp→ t-chto at the Large Hadron Collider (LHC), which proceeds through the parton-level processes gg→ t-chto , uu→ t-chto and d-d → t-chto . We calculate the production rate and present the distributions of the transverse momenta and the invarient mass of the neutral top-higgs. It is found that the cross section of pp→ t-chto can reach a few hundreds of fb in a large part of the allowed parameter space. Considering the main decay mode of top-higgs for mht〈2mt, we find that such a production may provide copious events. In the case of unobservation, the LHC can set meaningful constraints on the TC2 model.
