Tensor spin polarization induced by curved freeze-out hypersurface
Zhong-Hua Zhang, Xu-Guang Huang
We investigate how the curvature of the freeze-out hypersurface polarizes massive vector bosons in relativistic heavy-ion collisions. Starting from the Proca Lagrangian and using t…

Hydrodynamics of dilation and spin currents
Zhong-Hua Zhang, Xi-Hu Lv, Xu-Guang Huang
We formulate a relativistic hydrodynamic theory for fluids with spin and intrinsic dilation charges. Using an entropy-current analysis, we derive constitutive relations featuring a…

Vector and Tensor Spin Polarization for Vector Bosons at Local Equilibrium
Zhong-Hua Zhang, Xu-Guang Huang, Francesco Becattini +1
We derive expressions for the vector and tensor components of the spin polarization of massive vector bosons at local thermodynamic equilibrium up to second order in the space-time…
