Ourstudies show that the cross section σ(e~+ e~- → tbΠ_t~-) Teaches the level of tens of fb andσ(e~+ e~- → W~+Π_t~-) reaches the level of a few fb. With the yearly integrated luminosity of ￡～ 500 fb~(-1) expected at the planned colliders, one could collect thousands of charged top-pion ofevents via the process e~+ e~- → tbΠ_t~- and hundreds of events via the process e~+ e~- →W~+Π_t~-. The flavor changing decay mode Π_t~- → bc is the best channel to detect chargedtop-pion due to the clean SM background. With a large number of events and the clean background, thecharged top-pion should be observable at the planned colliders. Therefore, our studies in thispaper can help us to search for charged top-pion, and furthermore, to test the TC2 model.展开更多
