abstract

Heavy ion collisions generate strong fluid vorticty in the produced hot quark-gluon matter which could in turn induce measurable spin polarization of hadrons. We review recent progress on the vorticity formation and spin polarization in heavy ion collisions with transport models. We present an introduction to the fluid vorticity in non-relativistic and relativistic hydrodynamics and address various properties of the vorticity formed in heavy ion collisions. We discuss the spin polarization in a vortical fluid using the Wigner function formalism in which we derive the freeze-out formula for the spin polarization. Finally we give a brief overview of recent theoretical results for both the global and local spin polarization of $\Lambda$ and $\bar\Lambda$ hyperons.

  1. Spin Femtoscopy: A Framework for Revealing Genuine Spin Correlations

    nucl-th 2026-07 unverdicted novelty 8.0

    Spin femtoscopy is proposed to separate genuine two-particle spin correlations from quantum statistics and final-state interaction effects via spin-sensitive correlation functions on Lambda pairs.

  2. Chromomagnetic condensation and perturbative confinement induced by imaginary rotation in SU(2) Yang-Mills Theory

    hep-ph 2026-02 conditional novelty 7.0

    In SU(2) Yang-Mills, imaginary rotation is shown to induce a chromomagnetic condensate and to turn the perturbative confinement transition first-order, with phase boundary approaching Ω̃_c = π/√3.

  3. Fluid Acceleration in Heavy-Ion Collisions

    nucl-th 2026-03 conditional novelty 6.0

    In AMPT and UrQMD simulations, fluid acceleration in heavy-ion collisions reaches a few hundred MeV, peaks at fireball boundaries, and evolves from stopping-dominated deceleration at low energies to boundary/tilt puls...

  4. Tensor spin polarization induced by curved freeze-out hypersurface

    hep-ph 2025-09 conditional novelty 6.0

    The curvature of the freeze-out hypersurface induces a tensor spin polarization of vector mesons at leading gradient order, with predicted phi-meson spin alignment around -10^-4 to -10^-3.

  5. Linear sigma model with quarks and Polyakov loop in rotation: phase diagrams, Tolman-Ehrenfest law and mechanical properties

    hep-ph 2026-05 unverdicted novelty 4.0

    Comparison of SMASH and McDipper initial condition models shows agreement in longitudinal deposition at lower energies but substantial differences in energy and baryon deposition at higher center-of-mass energies.

  7. Chromomagnetic Condensate in Finite-Temperature SU(2) Yang-Mills Theory under Imaginary Rotation

    hep-ph 2026-02 conditional novelty 4.0

    At one loop, imaginary rotation in the SU(2) Savvidy model enhances the chromomagnetic condensate and effective coupling, can suppress the Nielsen-Olesen instability in a finite window, and gives a negative moment-of-...
