In the framework of the topcolor-assisted technicolor (TC2) model, we study
production of the neutral top-pion πt0​ in association with a
high-pT​ jet at the LHC, which proceeds via the partonic processes
gg⟶πt0​g, gq⟶πt0​q,
qqˉ​⟶πt0​g, gb(bˉ)⟶πt0​b(bˉ), and bbˉ⟶πt0​g. We find
that it is very challenging to detect the neutral top-pion πt0​ via
the process pp⟶πt0​+jet+X→ttˉ+jet+X, while the
possible signatures of πt0​ might be detected via the process
pp⟶πt0​+jet+X→(tˉc+tcˉ)+jet+X at the LHC.Comment: 13 pages, 4 figures; typos correcte
