Description
We argue that spin alignment of hadrons of spin 1 and higher provide a unique window into the study of hydrodynamics with spin, because it is capable to probe non-equilibrium between spin density and vorticity.
This happens because most of the full 3X3 density matrix is in principle accessible experimentally, and non-zero off-diagonal matrix elements can be directly linked to such non-equilibrium.
We illustrate this using a coalescence model for light vector mesons [1] as well as a potential model for quarkonia, and compare our calculations to experimental data [2].
