Neutral top-pion and top-charm production in high energy $e^{+}{e}^{-}$ collisions

Chongxing Yue, Gongru Lu, Junjie Cao +2

We calculate the contributions of the neutral top-pion, predicted by topcolor-assisted technicolor (TC2) theory, to top-charm production via the processes $γγ\longrightarrow\bar{t}…
