Description
In this talk, I will discuss the effects of the QCD critical point on polarization of spin-1/2 particles, in particular Λ hyperons, in local thermodynamic equilibrium. For this  purpose, we evaluate thermal vorticity by numerically solving the equations of relativistic causal hydrodynamics in (3+1) dimensions. The effects of the critical point are incorporated through the equation of state and the scaling behaviour of the transport coefficients. Our results suggest that the change induced by the critical point in the rapidity dependence of the spin polarization of Λ hyperons can be used as an indicator of the critical point.
