Description

The single neutral top-pion production process e+e-→νeν-bareΠ0t is studied in the framework of the top-colour-assisted technicolour model. The results show that the cross section can be significantly enhanced with the centre of mass energy increasing or the incoming beams being polarized. The cross section is over 0.1 fb provided √s = 1600 GeV or √s = 800 GeV with polarized incoming beams. The flavour-changing channel t-barc is the best one to search for the neutral top-pion due to the clean background. Such a process offers a complementary method to probe for neutral top-pion if enough luminosity is collected at the future colliders
