Description
We show that vector and higher spin resonances are a sensitive probe of a fundamental aspect of spin hydrodynamics - the lack of equilibrium between spin and vorticity. This is because the purity structure of the density matrix is measurable via the off-diagonal density matrix elements.
We illustrate this via coalescence models for light mesons and potential models for quarkonium states, and illustrate further directions for both theory and experimental analysis.
