Generating tensor polarization from shear stress

We derive an expression for the tensor polarization of a system massive spin-1 particles in hydrodynamic framework. Starting from quantum kinetic theory based on Wigner-function formalism, we employ modified method moments which also takes into account all spin degrees freedom. It is shown that uncharged fluid determined by shear-stress tensor. In order to quantify this novel effect, provide formula can be used numerical calculations vector-meson alignment relativistic heavy-ion collisions.
