“…Let us note that while correlation (5) may indeed signal the apperance of ringlike structure, it may also appear in inclusive polarization, similar to hadronic case [9][10][11][12]. Note that this case was actually a guideline in [15] and that inclusive polarization in HIC was recently studied in the course of preparations for experiments at NICA [23].…”

The interplay between classical vorticity being the main undisputed source of polarization in heavy-ion collisions (HIC) and quantized vortices is considered. The vortex tubes emerging in the rotating pionic (super) fluid polarize the baryons in their cores and explain the emerging global polarization. The appearance of vortices in the region separating participants and spectators in non-central HIC is similar to that for sliding layers of liquid helium. From the other side, it is also the region where the classical vorticity was earlier found to be large forming the vortex sheets. The formation of tubes manifests a threshold at certain critical vorticity implying the vanishing polarization at lower energies. For central HIC the compact jet-like flows may lead to formation of vortex rings related to local polarization. The P-odd momentum correlations for their experimental investigation are suggested. The role of shear and viscosity in the emergence of polarization is discussed.

“…The cosine (21) corresponding to scattering is larger (and, consequently, the polarization (20) is smaller) if the scattering angles (22) are of the same sign, so that the polarization will be larger after the single scattering described by the angle θ t . At the same time, if the scattering angles are of different sign, the polarization due to the single scattering is smaller than described by (21) and can be even zero if θ 0 = −θ s0 .…”

“…The scattering may also happen at numerous nucleons, and the suppression of polarization due to the randomization of the orientations of respective scattering planes was suggested [20] as a signal of strongly interacting matter formation. At the same time, the complementary investigation of respective inclusive polarization [21] provides the quantitative estimates of these randomization effects so that the composition law for polarization generated at different stages of hyperon production process is also of importance.…”

The polarization emerging in the subsequent scattering processes can never exceed 1 which corresponds to the fully polarized pure state. This property is shown to be provided by the addition rule similar to that for relativistic velocities never exceeding the speed of light. The cases of spin 1/2 and 1 are considered. The photon linear polarization in Thomson scattering is monotonically increasing. This directness is shown to be a consequence of spin measurement procedure and may be the particular example of ithe anticipated relation between quantum measurement and time irreversibility. The emergent polarization may be considered as a case of opposing time's arrows corresponding to microscopic (spin) and macroscopic (momentum) degrees of freedom, respectively.
