Abstract

We present a new Lagrangian approach for the dynamical structure of the generalized Proca theory (GP). This approach includes the A-Z constraint structure of the model in the Lagrangian formalism and ends up with an accurate count of the number of degrees of freedom. We also give the complete Hamiltonian constraint structure of the model.
