  We present cross-correlators of QCD conserved charges at $\mu_B=0$ from
lattice simulations and perform a Hadron Resonance Gas (HRG) model analysis to
break down the hadronic contributions to these correlators. We construct a
suitable hadronic proxy for the ratio $-\chi_{11}^{BS}/\chi_2^S$ and discuss
the dependence on the chemical potential and experimental cuts. We then perform
a comparison to preliminary STAR results and comment on a possible direct
comparison of lattice and experiment.
