Equation of state for distributed mass quark matter
arXiv:hep-ph/0605274 · doi:10.1088/0954-3899/32/12/S26
Abstract
We investigate how the QCD equation of state can be reconstructed by a continous mass distribution of non-interacting ideal components. We find that adjusting the mass scale as a function of the temperature leads to results which are conform to the quasiparticle model, but a temperature independent distribution also may fit lattice results. The fitted mass distribution tends to show a mass gap, supporting the physical picture of the quark coalescence in hadronization.
