RESUMO
There is a recent proposal of identifying the Higgs particle of the Standard Model as a pseudo Nambu-Goldstone boson. This new broken symmetry introduces new particles and new interactions. Among these new interactions a central role to get an experimental signal of a new physics is played by the new neutral gauge bosons, A H and Z H. We study the associated production of general new neutral gauge boson Z¢ and a hard photon in the process e+ + e- ® m + + µ- + gamma. For M AH < ÖS we show that the hard photon energy distribution in e+ + e- ® g + f + f can present a model dependence and establish the theoretical origin of a new possible heavy neutral gauge boson.
