2302.11826_Qtraj regeneration
Recent lattice measurements favor larger $\hat\kappa$ and $\hat\gamma\approx 0$.
With $\hat\kappa = 4$ and $\hat\gamma = 0$ good agreement with experimental data
Quantum regeneration ($o\to s$) neccessary to explain data, $H_{eff}$ can not account.
Future: Explore temperature dependence in transport coefficients ?? ($\gamma(T) \neq \hat\gamma T^3$ ?)
