New Mechanism for Mass Generation of Gauge Fields
  A new mechanism for mass generation of gauge fields is proposed in this paper. By introducing two sets of gauge fields and making the variatons of these two sets of gauge fields compensate each other under local gauge transformations, the mass term of gauge fields can be introduced into the Lagrangian without violation the local gauge symmetry of the Lagrangian. Besides, this model is renormalizable.
