The process e(+)e(-) -> nu(nu)over-bar gamma in topcolour-assisted technicolour models

摘要

In the context of topcolour-assisted technicolour (TC2) models, we consider the process e(+)e(-) --> upsilon(υ) over bar gamma and calculate the cross section of this process at leading order. It is shown that the extra U(l) gauge boson Z' predicted by TC2 models can give significant contributions to the process e(+)e(-) --> nu(tau)(ν) over bar (tau)gamma, which may be detected in the future high energy linear e(+)e(-) collider (LC) experiments.
