We study susceptibilities of real and imaginary parts as well as modulus of the Polyakov loop in an effective model of gluons and quarks. In pure SU(3) gauge theory, the ratios of these susceptibilities exhibit a clear discontinuity at the deconfinement temperature while ratios calculated in 2+1 QCD become smoothened and vary between corresponding pure gauge asymptotic values. This suggests...

22. Dissociation of hadrons in hot dense matter

A unified equation of state for quark-hadron matter is presented in the generalized Beth-Uhlenbeck form. It follows from a Φ−derivable approach to the thermodynamic potential where the ansatz for the Φ functional contains all 2PI diagrams at two-loop order formed with quark cluster Green's functions for quark, diquark, meson and baryon propagators. We present numerical results using an...
