Abstract
We have computed the second Fourier sine coefficient of the longitudinal spin polarization, 〈Pz sin 2(ϕp – Ψ2)〉, as a function of multiplicity or centrality in Au+Au collisions at √sNN = 200 GeV and in p+Pb collisions at √sNN = 8.16 TeV using the CLVisc hydrodynamic framework. The numerical results successfully describe the data in Au+Au collisions. However, understanding the data in p+Pb collisions remains a puzzle. Additionally, we have reported some recent developments in quantum kinetic theory and spin hydrodynamics.
