+The general solution for the Proca equation is
+\begin{align} A_\mu &=  \int \frac{d^3 k}{\sqrt{ (2\pi)^3 2 \omega_k}} \left( \epsilon_{r,\mu}(k) a_r(k) {\mathrm{e}}^{-ikx} + \epsilon_{r,\mu}(k) a_r^\dagger(k) {\mathrm{e}}^{ikx}  \right) \notag \\
+ \label{eq:aplusminus} &\equiv  A_\mu^+ + A_\mu^-   \end{align}
+where $\epsilon_{r,\mu}(k)$ are basis vectors called polarization vectors.
