Susceptibilities: Test of Mu Dependence 10% problem data: Allton et al., Nf = 2
also good agreement with Gavai-Gupta data for data: Allton et al., Nf = 2 sensible test of flow eq. & baryon charge carriers (no di-quarks etc. needed)

Conclusions 2-loop Γ+ HTL + g G: - good fits of EoS - small contributions of plasmon, plasmino, Landau damp. effective QPM: only T gluons + quarks, simpl. disp. rel. - imaginary mu - high T - susceptibilities - useable EoS for RHIC + LHC elementary excitations in QGP = ? lattice QCD spectral functions, propagators (transport coefficients)
