[tex] S=\int d^4x\frac{m}{12}A_μ ε^{μ \nu ρσ} H_{\nu ρσ} + \frac{1}{8} m^2A^μA_μ [/tex]
Where
[tex] H_{\nu ρσ} = \partial_\nu B_{ρσ} + \partial_ρ B_{σ\nu} + \partial_σ B_{\nu ρ} [/tex]
And [itex] B^{μ \nu} [/itex] is an antisymmetric tensor.
What are the global symmetries and what are the local symmetries?
p.s how many degrees of freedom does it have?
Thank you!
