Description

We show how repulsive interactions of deconfined quarks as well as confined hadrons can be constrained in a straight forward way by model comparisons of baryon number susceptibilities with lattice QCD results . We also discuss implications for earlier constraints, extracted from the curvature of the transition line of QCD and compact star observables. Our results clearly point to a strong vector repulsion in the hadronic phase and near-zero repulsion in the deconfined phase.
