Might it be $L^{\nu}=(0, \vec L)$, where $\vec L=\int\,\vec p \times \vec r\,dV$ is the three dimensional angular momentum? But latter would hold only for low angular velocities. What is the angular momentum vector in Special Relativity? We must use the four dimensional vectors. But the product $\epsilon_{\nu \mu \alpha \beta}\,p^{\alpha}\,x^{\beta}$ is not a vector, but the tensor.
