Abstract：
In the framework of the topcolor-assisted technicolor (TC2) model, we study the production of the neutral top-pion π_t⁰ in association with a high-p_T jet at the LHC, which proceeds via the partonic processes gg→π_t⁰g, gq→π_t⁰q, qq→π_t⁰g, gb(b)→π_t⁰b(b), and bb→π_t⁰g. We find that it is very challenging to detect the neutral top-pion π_t⁰ via the process pp→π_t⁰+jet+X→tt+jet+X, while the possible signatures of π_t⁰ might be detected via the process pp→π_t⁰+jet+X→(tc+tc)+jet+X at the LHC.
