- We calculate the spin density matrix for neutral $ρ$ mesons from the spectral function and thermal shear tensor by Kubo formula in the linear response theory, which contributes to the $γ$ correlator for the CME search. We derive the spectral function of neutral $ρ$ mesons with $ρππ$ and $ρρππ$ interactions using the Dyson-Schwinger equation. The thermal shear tensor contribution is obtained from the Kubo formula in the linear response theory. We numerically calculate $ρ_{00}-1/3$ and $\mathrm{Re}ρ_{-1,1}$ using the simulation results for the thermal shear tensor by the hydrodynamical model, which are of the order $10^{-3}\sim10^{-2}$.
