We propose to probe the topcolor-assisted technicolor (TC2) model from thetop-charm associated productions at the LHC, which are highly suppressed in theStandard Model. Due to the flavor-changing couplings of the top quark with thescalars (top-pions and top-Higgs) in TC2 model, the top-charm associatedproductions can occur via both the s-channel and t-channel parton processes byexchanging a scalar field at the LHC. We examined these processes through MonteCarlo simulation and found that they can reach the observable level at the LHCin quite a large part of the parameter space of the TC2 model.Comment: Version to appear in PRD (Rapid Communication
