In the context of topcolor assisted technicolor(TC2) models, we study the
production of the top-pions Οt0,Β±β with single top quark via the
processes ppΛββtΟt0β+X and ppΛββtΟtΒ±β+X,
and discuss the possibility of detecting these new particles at Tevatron and
LHC. We find that it is very difficult to observe the signals of these
particles via these processes at Tevatron, while the neutral and charged
top-pions Οt0β and ΟtΒ±β can be detecting via considering
the same sign top pair ttcΛ event and the ttbΛ (or ttΛb)
event at LHC, respectively.Comment: latex files,14 pages, 7 figures. Accepted for publication in Phys.
