The model has SU(N) gauge symmetry. In the limit $α\longrightarrow 0$, the gauge field model discussed in this paper will return to Yang-Mills gauge field model. The important meaning of this model is that, without Higgs mechanism, gauge bosons can also obtain masses. This theory can also explain some other unknown phenomenum.5 Pages, no figures, LaTex fileHigh Energy Physics - Phenomenologytext
