Gauge-invariant Lagrangian for Poincare group

Possibility of constructing gauge-invariant action for the Poincare group satisfying its physical requirements has been analysed using the method suggested before. It is shown that such action is impossible to construct in case of accurate symmetry and it is possible to construct it with spontaneous symmetry violation. In this case the possibility of existence of massive vector particles corresponding to the gauge fields of the translation subgroup occurs
