8 Dec 2002 | | Journal: | Phys.Rev. D67 (2003) 071701 | | Subject: | hep-ph hep-ex | | Abstract: | We propose to probe the topcolor-assisted technicolor (TC2) model from the top-charm associated productions at the LHC, which are highly suppressed in the Standard Model. Due to the flavor-changing couplings of the top quark with the scalars (top-pions and top-Higgs) in TC2 model, the top-charm associated productions can occur via both the s-channel and t-channel parton processes by exchanging a scalar field at the LHC. We examined these processes through Monte Carlo simulation and found that they can reach the observable level at the LHC in quite a large part of the parameter space of the TC2 model. | | Source: | arXiv, hep-ph/0212114 | | Services: | Forum | Review | PDF | Favorites | |
