abstract
We propose that a significant positive deviation from 1/3 for the spin density matrix element $\rho_{00}$ of the $\phi$ meson may indicate the existence of a mean field of the $\phi$ meson generated in heavy-ion collisions. This explains why STAR preliminary data for the $\phi$ meson's $\rho_{00}$ are much larger than 1/3 while the data of $\Lambda$ and $\bar{\Lambda}$ polarization seem not to allow such a significant and positive deviation. The contribution may be from the polarization of the strange quark and antiquark through the $\phi$ field, an effective mode of the gluon field in strong interaction. We show that $\rho_{00}$ for the $\phi$ meson is a good analyzer for fields even if they may strongly fluctuate in space-time.

Spectral Functions of $J/\psi$ Meson in Rotating Thermal Background from Holography
In a rotating thermal medium modeled by soft-wall holography, J/ψ spectral peaks split by −ΩJ_z along the rotation axis and acquire projection-dependent distortions for transverse momentum.

Tensor spin polarization induced by curved freeze-out hypersurface
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.

Is the shear induced spin polarization non-dissipative?
Shear-induced spin polarization leaves the momentum-integrated entropy production rate unchanged in chiral kinetic theory, but Zubarev's linear response suggests a dissipative origin.

Exploring Data-Driven Corrections for $\phi$-Meson Global Spin Alignment Measurements
A data-driven correction built from combinatorial kaon pairs inside the phi mass window is tested with toy Monte Carlo, showing partial success and clear shortcomings.

Impact of Tracking Resolutions on $\phi$-Meson Spin Alignment Measurement
Track angular and momentum resolutions shift the extracted phi-meson spin alignment parameter rho_00 by less than 0.0005 in STAR-like toy-model simulations, though the invariant-mass method's conversion formula is wrong.

Experimental Search for the Chiral Magnetic Effect in Relativistic Heavy-Ion Collisions: A Perspective
The chiral magnetic effect in heavy-ion collisions remains unconfirmed, with current data giving a 2.9-sigma hint in Au+Au and an upper limit near 10% in isobar collisions.
